Q

When to give IV fluids?

A

Heart rate:Healthcare providers should consider fluid administration when the heart rate exceeds 90 bpm. Tachycardia may indicate a compensatory physiological response to preserve perfusion in hypovolemia and can manifest as an early sign of compensated hypovolemic shock. Nonetheless, tachycardia can have various other causes, including pain, fever, and anxiety.

Blood pressure:Healthcare providers should contemplate fluid administration when the systolic blood pressure falls below 100 mm Hg. A declining blood pressure is an ominous finding often linked with tachycardia. Hypotension and tachycardia indicate that the cardiovascular system can no longer compensate for hypovolemia effectively. Conversely, elevated blood pressure is typically associated with hypervolemia.

Orthostatic vital signs:These signs involve a reduction of at least 20 mm Hg in systolic blood pressure or 10 mm Hg in diastolic blood pressure within 2 to 5 minutes of standing quietly after 5 minutes of supine rest, which signifies the presence of orthostatic hypotension.[6]These findings may be evident in dehydrated or older patients who have experienced reduced sensitivity in the baroreceptors of their blood vessels.

Respiratory rate:Healthcare providers should contemplate fluid administration when the patient’s respiratory rate exceeds 20 breaths per minute. An elevated respiratory rate suggests a compensatory response to metabolic acidosis resulting from lactic acidosis due to inadequate tissue perfusion.

Urine output:In clinical practice, healthcare providers should anticipate a minimum urine output of 1.5 mL/kg/h in children and more than 1 mL/kg/h in adults. Specific clinical scenarios may necessitate higher urine output thresholds to minimize the risk of renal toxicity, especially when administering nephrotoxic medicationssuch asacyclovir.

31
Q

Ischemic stroke vs hemorrhage stroke

A

Ischemic stroke: stroke that can be either caused by plaque- thrombosis (atherosclerosis) or blood causes emboli. Because of the emboli, not enough blood or no blood can come to the area of needed like brain and this obstruction causes lack of supply of blood/oxygen needed. Treatment: We want high BP, around 160-180 is fine, so enough blood flow can be given to areas of needed oxygen/blood supply.
Hemmorrhage stroke: stroke that is caused by long time hypertension, and can cause bleeding in the cerebral arteries and blood filled in the brain which is seriously emergency case. We want BP to be low because we don’t want no more bleeding
Might need coronary artery bypass graft surgery.

32
Q

Pain assess scales use explain

A
  1. Numeric scale: number scales to assess pain level for patient severity where 0 is no pain and 10 is the most pain ever imagined. Can use picture to demonstrate from facility. Use for patients who can follow directions
  2. PQRST: A combined pain assessment with numeric scale. More details and used for general patients who understand and comprehend language/conscious mind
    P – Provocation or Palliation: This refers to what provokes or alleviates the pain. Healthcare providers may ask patients what triggers their pain or makes it worse and what makes it feel better. For example, the patient may report that certain activities or movements worsen their pain, or that it is alleviated by rest or medication.
    Q – Quality refers to the pain’s nature or quality. Healthcare providers may ask patients to describe their pain in their own words. For example, the patient may describe their pain as sharp, dull, throbbing, or burning.
    R – Region or Radiation: This letter refers to where the pain is located and if it radiates to other body areas. Healthcare providers may ask patients to point to where the pain is located and if it spreads to other areas. For example, a patient may report pain in their left arm that radiates up to their shoulder.
    S – Severity: This letter refers to the intensity of the pain. Healthcare providers may ask patients to rate their pain on a scale of 0-10, with 0 being no pain and 10 being the worst pain imaginable. This rating can help healthcare providers understand how severe the pain is and how it impacts the patient’s daily life.
    T – Timing: This letter refers to when the pain occurs and how long it lasts. Healthcare providers may ask patients how long they have been experiencing pain, if it is constant or intermittent, and if it occurs at a certain time of day or in response to certain activities.
  3. FLACC: Used for patients who understand the process but can’t verbalize back.
    0 is the least point and 10 is the maximum point can have. Face (angry, happy, frowning/grumpy). Leg (is patient normal position/relaxed or uneasy or kicking), activity (is pt lying quietly or moving back and forth or patient is stiff, jerking or rigid), cry (is patient have no expression, or moan or crying steadily), consoling (relaxed or patient needs hug/touch/talking/distraction or these don’t help at all)
  4. PAINAD: basically the same as FLACC scale but used for advanced dementia patients.
    0 is the least and 10 is the maximum point can get. Need to see for breathing as extra with FLACC (is patient breathing normally, rapid or hyperventilate/presenting Cheyne’s stokes breathing)
33
Q

CO2 retainers patients

A

Patient can have low O2 levels. Be mindful that the O2 supplemental therapy should not be high where titrate fio2 should be from 88-92% because too much O2 makes patient loss the drive to breath.
CO2 retention is known as hypercapnia or hypercarbia. Hypercapnia is often caused by hypoventilation or failure to remove excess CO2 and may be diagnosed by an arterial or venous blood gas. Elevations of CO2 in the bloodstream can lead to respiratory acidosis. Normal respiratory drive, and thus CO2 exhalation, is primarily maintained by the chemoreceptor reflex. The chemoreceptor reflex is important in allowing the body to respond to changes in pO2, pCO2, and pH. Chemoreceptors can be categorized as peripheral or central. Peripheral chemoreceptors are located in the carotid and aortic bodies. The carotid body is the principal sensor of increased pCO2, decreased pO2, and overall decreased pH. The glomus cells of the carotid body relay changes in peripheral arterial pH to the central nervous system via the glossopharyngeal nerve. [1]

Central chemoreceptors are located near the ventrolateral surfaces of the medulla. While peripheral chemoreceptors are primarily sensitive to changes O2 and CO2, central chemoreceptors are responsive to changes in pCO2 and pH. Central chemoreceptors are able to rapidly detect changes in PCO2. The blood-brain barrier is permeable to CO2, thus allowing chemosensitive cells within the medulla to respond to elevations in blood CO2, and the subsequently lowered pH. The decrease in pH of the cerebrospinal fluid ultimately increases minute ventilation, defined by the product of respiratory rate and tidal volume. Interestingly, central chemoreceptors have shown a greater response to hypercapnic acidosis rather than isocapnic acidosis, in part likely due to the impermeability of the blood-brain barrier to H+ ions. As a result, the sympathetic outflow to the vasculature is increased, and efforts are made to increase the respiratory rate.

34
Q

How to identify stroke

A

BEFAST:
1. Balance: signs for dizziness, stumble to stand/loss of balance
2. Eyes: blurred vision
2. Face: one side drooling. Ask patient to smile and see if still symmetry
3. Arms: one side weakness (arm or leg). Ask patients to raise both arms and see if one drift downward
4. Speech: speech dificulty, slurred speech. Ask patient to say something and is it strange
5. Time: call 911

35
Q

Different settings for frequency of vital signs assessment

A

ICU: Q1H
Telemetry: Q4H
Medical-surgical: Q8H
However, each patient is different. Whenever there is a change in condition, or when patient complains about their condition, or when patient need to do surgery either pre or postoperative, or when upon administration, specific orders and according to the rules of each facility.

36
Q

Body temp notes

A

Sites of surface temperatures route: oral, axillary, temporal (scanning infrared)
Sites of core temperatures route: rectal, tympanic (infrared)
Can be lower in the morning and more at afternoon. Can increase when there’s increase in cells metabolic rate like ovulation, hormones like estrogen excretion, hyperthyroidism, etc.

37
Q

Hypothermia

A

Early rise in BP, HR, and RR. However, if can not control, overtime, body can experience low BP, undetectable pulse and RR (low RR and low HR). As body loses control where mostly body would vasoconstriction to keep heat, but because of this, vasodilations cause loss of heat and people can sweat more when hypothermia so make sure give towels to dry skin otherwise colder after sweating. Make sure patient having enough hydration (offer warm fluids, warm heated blankets, bair hugger after or before surgery).

38
Q

Fever noticeable notes

A

If patient is experiencing fever, we can adjust the temperature and if patient have thick blankets, then take off. If patient asks for it, bring lightweight blankets. Monitor skin and other vital signs (might have to blood lab values). Can bring in fan to have more air. Can give antipyretic (if have liver problems like liver cirrhosis, then can ibuprofen, or aspirin). We don’t want shivers, don’t want activity that can increase metabolic rate.

39
Q

When assess the pulse, what to notice

A

Rate (60-100 bpm), rhythm (irregular or regular) strength (0,1,2,3) , equality (is both sides lateral)

40
Q

Important notes

A

In men, increase respiratory rate increase in total peripheral pressure and cause decrease in heart rate and decrease in cardiac output. There is no correlation shown in women.

41
Q
