67
HFpEF VS HFrEF

HFrEF - systolic failure
68
Which assessment finding is consistent with right-sided heart failure (HF)?
Jugular Vein Distention (JVD)
Presence of S3 and S4 heart sounds
Paroxysmal Nocturnal Dyspnea (PND)
Displacement of the point of maximal impulse (PMI)
Jugular Vein Distention
JVD is a sign of right sided HF. Right-sided HF occurs when the right ventricle does not pump effectively. When the RV fails, fluid backs up into the venous system. That causes movement of fluid into the tissues and organs (e.g. peripheral edema, abdominal ascites, hepatomegaly, JVD. All the other choices are associated with LEFT sided HF.
68
When teaching drug therapy for chronic heart failure, the nurse would explain that which mechanism is blocked by angiotensin-converting enzyme (ACE) inhibitors?
Aldosterone-secreting effects of angiotensin II
Natriuretic peptide system
Conversion of angiotensin I to angiotensin II
Aldosterone activation
C. Conversion of Angiotensin I to Angiotensin II
ACE inhibitors block the renin-angiotensin-aldosterone System (RAAS) by inhibiting the conversion of angiotensin I to II. ACE inhibitors are first-line drugs in patients with heart failure with reduced ejection fraction (HFrEF). They reduce afterload and systemic vascular resistance (SVR) and slow ventricular remodeling by inhibiting ventricular hypertrophy.
69
Which primary manifestation results from the decreased filling of the cardiac ventricles associated with diastolic failure?
Decreased afterload
Decreased left ventricular ejection fraction
Decreased left ventricular end-diastolic pressure
Decreased stroke volume and cardiac output
D. Decreased Stroke Volume and Cardiac Output
HF with preserved ejection fraction HFpEF is DIASTOLIC Failure. It results from the inability of the ventricles to relax and fill during diastole. Decreased filling volume in the ventricles results in decreased stroke volume and reduced cardiac output. Diastolic failures are characterized by high filling pressures because of stiff ventricles, increasing afterload, and left ventricular end-diastolic pressure. Venous engorgement in both the pulmonary and systemic vascular systems causes a decreased left ventricular ejection fraction. In HFpEF, the left ventricle is generally stiff and noncompliant, causing high filling pressures.
69
The nurse would monitor for which side effect in a patient who takes an angiotensin-converting enzyme (ACE) inhibitor to treat chronic heart failure (HF)?
Cough
Anemia
Hyperpigmentation
Increased body temperature
Cough
ACE inhibitors can cause a dry, persistent cough due to increased bradykinin levels.
69
Jugular Vein Distention (JVD) is a sign of ____________
right sided HF
70
ACE inhibitors can cause a ___________________ due to increased bradykinin levels.
dry, persistent cough
71
The nurse would question which item that is listed on a hospital discharge plan for a patient with chronic heart failure?
Eat small, frequent meals
Obtain the annual flu vaccine
Avoid extremes of heat and cold
Report a weight gain of 3 pounds in one week
D. Report a weight gain of 3 lbs in one week
The nurse should tell patients to call the HCP about a weight gain of 3 lb over 2 days or a 3-5 lb gain over a week. Eating small, frequent meals is a component of dietary therapy. The patient should be instructed to receive the annual flu vaccination for health promotion. The patient should be instructed to avoid extremes of heat and cold to prevent stress on the heart
72
A patient with hypertension has been prescribed an antihypertensive medication. During a follow-up visit, the patient asks whether the medication can be stopped because the blood pressure (BP) is now within the normal range. Which response would the nurse provide?
"you may stop the medication now because your BP is normal"
"begin taking half-doses of the medication because the BP has decreased"
"you may stop taking the medication only if you maintain a healthy lifestyle"
"continue the medication unless your HCP advises discontinuing it"
D. "continue the medication unless your HCP advises discontinuing it"
Antihypertensive medications are effective at reducing BP. However, the medications should not be stopped abruptly because this can cause severe hypertensive reaction. The medications should be discontinued only after consulting with the HCP. The medication should not be stopped even if the BP measurements show normal readings. Medications should be taken regularly for sustained therapeutic effects.
73
A client is admitted following a thrombotic stroke. What priority assessment is most important to perform in the first 24 hrs?
a. 12 lead EKG
b. Assess if bowel sounds are hypo or hyperactive
c. Pupil size and pupillary response
d. Coagulation lab test
c. Pupil size and pupillary response
The nurse should assess pupil size and pupillary responses, which may indicate changes associated with the complications of the stroke. Neuro assessment is the first priority with a stroke patient.
74
The emergency department nurse receives a client with an ischemic stroke, and prepares to administer tissue plasminogen activator (t-PA). What question should the nurse ask first before administering the t-PA?
a. Ask the client which arm or leg is affected.
b. Ask the client if speech was slurred.
c. The nurse will ask the time of onset of stroke.
d. Ask what home medications the client takes.
c. The nurse will ask the time of onset of stroke
The emergent need is to determine if the client is a candidate for t-PA administration. Timing of onset of stroke is important when receiving t-PA. The patient should receive thrombolytic medication with in 3-4.5 hours after the onset of a stroke for best outcomes.
75
Which patient statement supports a history of intermittent claudication?
a. “When I stand too long, my feet start to swell.”
b. “My legs cramp when I walk more than a block.”
c. “I get short of breath when I climb a lot of stairs.”
d. “My fingers hurt when I go outside in cold weather.”
b. “My legs cramp when I walk more than a block.”
Cramping that is precipitated by a consistent level of exercise is descriptive of intermittent claudication. Finger pain associated with cold weather is typical of Raynaud’s phenomenon. Shortness of breath that occurs with exercise is not typical of intermittent claudication, which is reproducible. Swelling associated with prolonged standing is typical of venous disease.
76
Cramping that is precipitated by a consistent level of exercise is descriptive of _________________________
intermittent claudication.
77
After teaching a patient with newly diagnosed Raynaud's phenomenon about how to manage the condition, which action by the patient best demonstrates that the teaching has been effective?
a. The patient exercises indoors during the winter months.
b. The patient immerses hands in hot water when they turn pale.
c. The patient takes pseudoephedrine (Sudafed) for cold symptoms.
d. The patient avoids taking nonsteroidal antiinflammatory drugs (NSAIDs).
The patient exercises indoors during the winter months.
Patients should avoid temperature extremes by exercising indoors when it is cold. To avoid burn injuries, the patient should use warm rather than hot water to warm the hands. Pseudoephedrine is a vasoconstrictor and should be avoided. There is no reason to avoid taking NSAIDs with Raynaud's phenomenon
78

-Hair loss to lower extremity
-Diminished or absent pulses
-Elevation pallor or reactive hyperemia (dependent rubor)- Leg Up & Down
