Question 1 of 5
A 28-year-old woman is admitted with suspected urinary sepsis (temperature 40.2°C, BP 84/50, pulse 128). She had a massive haemorrhage following the birth of her only child when she was aged 24; since then she has had no periods. Her partner says that she has been progressively listless and depressed for at least two years. There is left loin tenderness and she has no pubic or axillary hair. Which of the following would be most appropriate?
Correct Answer: B
Rationale: Sepsis (fever, hypotension) with post-partum hemorrhage history, amenorrhea, fatigue, and hair loss suggest Sheehan's syndrome (pituitary necrosis) causing adrenal insufficiency. Oral amoxicillin is inadequate for septic shock. IV hydrocortisone treats acute adrenal crisis, stabilizing BP and stress response, most appropriate here alongside antibiotics. Pelvic exam doesn't address urgency. Gonadotrophins or triiodothyronine target secondary issues, not immediate crisis. Hydrocortisone's rapid action is life-saving, addressing cortisol deficiency in this emergency.

Question 3 of 5
A client is prescribed phenytoin (Dilantin) for seizures. Which statement by the client indicates effective teaching?
Correct Answer: B
Rationale: Phenytoin risks gingival hyperplasia, making oral hygiene vital'brushing and flossing prevent this, showing teaching success. Alcohol increases seizure risk and drug levels. Milk reduces absorption via calcium binding. Stopping after a month risks recurrence, as seizures require long-term control. Regular dental care mitigates a common, chronic side effect, aligning with phenytoin's long-term use and metabolism (CYP450 saturation). This statement reflects understanding of self-care, critical for adherence and complication prevention, making B the indicator of effective education.
Question 4 of 5
A 42-year-old female who is obese and with a history of gallstones and cholecystitis complains of superficial skin swelling and itching. Physical examination by the primary care physician reveals skin erythema, tenderness, and swelling consistent with cellulitis. The patient is given a prescription for erythromycin. Which of the following effects must the treating physician be keenly aware of?
Correct Answer: A
Rationale: Erythromycin for cellulitis risks cholestatic jaundice , especially in patients with gallstone history. Abdominal discomfort , nausea , and vomiting (E) are common but less severe. Tinnitus is rare. Jaundice, from hepatic dysfunction, requires monitoring given her biliary background.
Question 5 of 5
A balanced anesthetic technique for production of general anesthesia may include which of the following drugs?
Correct Answer: D
Rationale: A balanced anesthetic technique for producing general anesthesia usually involves a combination of different types of drugs to achieve the desired level of unconsciousness, analgesia, muscle relaxation, and amnesia while minimizing adverse effects. The use of multiple drugs simultaneously allows for lower doses of each drug, reducing the risk of toxicity and adverse side effects. In a typical balanced anesthesia regimen, an inhalation anesthetic is used for the maintenance of anesthesia, a narcotic provides analgesia, a muscle relaxant is used to facilitate intubation and reduce muscle movements during surgery, and an IV barbiturate may be used as an induction agent to initiate anesthesia. Therefore, all of the options provided - an inhalation anesthetic, a narcotic, a muscle relaxant, and an IV barbiturate - are commonly included in a balanced anesthetic technique for producing general anesthesia.
