Clinical Management Flashcards

1
Q

A 16-year-old woman presents with secondary amenorrhoea. She is healthy, with no past medical history. Her BMI is 17. What is the most appropriate initial investigation?

A

The answer is follicle-stimulating hormone measurement. The likely diagnosis is amenorrhoea caused by weight loss, so follicle-stimulating hormone measurements would be appropriate.

Q

A 55-year-old woman presents to the clinic enquiring about the use of hormone replacement therapy (HRT). She had a hysterectomy 8 years ago for fibroids. She has no contraindications or other past medical history, except a strong family history of osteoporosis. Her main symptoms are hot flushes and vaginal dryness. What would be your first treatment option?

A

The answer is estrogen-only HRT. HRT provides the most effective method of treating climacteric hot flushes and vaginal dryness, as well as postmenopausal osteoporosis. Estrogen-only HRT is appropriate following a hysterectomy, as the risk of endometrial carcinoma is not present.

Q

An 18-year-old woman presents to an early pregnancy unit with light vaginal bleeding after 10 weeks of amenorrhea. She had taken a pregnancy test 4 weeks ago that had tested positive. A transvaginal ultrasound scan showed an irregular gestation sac with no fetal pole. What is the likely diagnosis?

A

The answer is anembryonic pregnancy.

In this case, the woman is considered to be pregnant, although no embryonic tissue is present. Therefore, the most likely diagnosis is anembryonic pregnancy.

Q

You are asked to assess a woman who is receiving magnesium sulphate infusions for severe pre-eclampsia. They have passed only 5 ml urine in the last 2 hours. Tests demonstrate that their deep tendon reflexes are absent. What other observation should you take?

A

The answer is respiratory rate. This woman has signs of magnesium toxicity (absent deep tendon reflexes), which is probably secondary to renal impairment. Respiratory depression is a sign of increasing magnesium toxicity.

Q

Polyglactin sutures are used extensively in surgical procedures, particularly to ligate vessels. What are the key features of polyglactin sutures?

A

Braided, absorbable and synthetic

Polyglactin sutures are used to ligate pedicles and close the uterus during a caesarean section.

Q

A 68-year-old woman presents with two episodes of postmenopausal bleeding. She has a BMI of 23 and is otherwise healthy. An ultrasound shows that her endometrial cavity is 4 mm thick, and an endometrial pipelle sample is taken that yields a small volume of tissue. The pathology report suggests a neoplasm. What is the most likely diagnosis?

A

The answer is serous carcinoma. Serous carcinomas are typically seen in postmenopausal women. The development of these carcinomas is not associated with a raised BMI, diabetes or hypertension.

Q

A 75-year-old woman presents with increased weight, loss of hair and a dislike of cold weather. She was noted to have a high prolactin and normal electrolytes. She is otherwise fit and well. What is the likely cause of the high prolactin?

A

Hypothyroidism

17
Q

or a ventouse delivery to be successful, the ventouse cup needs to be applied to the flexion point of the fetal head. Where on the fetal head is the flexion point located?

A

On the sagittal suture line, approximately 3 cm anterior (in front) of the posterior fontanelle

18
Q

Normal ABG values

A

pH 7.35-7.45
PaCO2: 4.5-6KPA or 35-45 mmHg
HCO3 22-26

19
Q

HBsAg POSITIVE
Anti-HBc POSITIVE
Anti-HBc IgM NEGATIVE
HBeAg NEGATIVE
Anti-HBe POSITIVE

diagnosis?

A

HBsAg is a marker of infectivity. Its presence indicates either acute or chronic HBV infection. Anti-HBc (IgG antibody to core antigen) usually remains positive for life following HBV infection. Anti-HBc IgM is found in high concentrations in acute infection, gradually declining and complementing the rise in Anti-HBc IgG. The presence of Anti-HBe suggests a low viral titre and a low degree of infectivity.

20
Q

The blood film shows polychromasia with numerous microspherocytes and occasional normoblasts. Increased reticulocytes. There is a slight increase in neutrophils. What is the most likely diagnosis?

A

Haemolytic anaemia

21
Q

Hypernatraemia after surgery is often caused by?

A

excessive intravenous dextrose. Hypernatraemia is common after excess IV normal saline but hyponatraemia can occur with excessive 5% dextrose IV.

22
Q

Potassium electrolyte disturbance is caused by increasing intracellular shift, caused by what?

A

Insulin

23
Q

What is the most common cause of macrocytic anaemia?

A

Alcohol

24
Q

A 54-year-old woman with known hypothyroidism presents with a sore red tongue and a lemon-tinged skin. Blood test results show a macrocytic anaemia. Diagnosis?

A

Pernicious anaemia

25
Q

What causes high calcium?

A

Multiple myeloma
hyperparathyroidism
Paget’s disease (with associated high ALP)

26

A

DNA fragmentation

27
Q

What test would you use to quantify proteinuria?
