Correct Answer: A

Rationale: A paradoxical pulse is a sign of cardiac tamponade, a life-threatening complication of pericarditis that requires immediate intervention. It results from decreased cardiac output due to increased pressure in the pericardial sac. Reporting this finding promptly allows for timely treatment to prevent further deterioration. Dependent edema and substernal chest pain are common in pericarditis but are not as urgent as a paradoxical pulse. A pericardial friction rub is a classic finding in pericarditis and indicates inflammation but is not as critical as a paradoxical pulse.

Correct Answer: D

Rationale: The correct answer is D. There is no need to limit fish intake with furosemide, indicating a misunderstanding of dietary restrictions. Furosemide is a diuretic that helps the body get rid of excess water and salt. Choices A, B, and C are all appropriate actions for a client taking furosemide. Taking morning pills with food or milk can help reduce stomach upset, weighing oneself daily helps monitor fluid retention, and notifying the nurse about muscle cramps can be important due to potential electrolyte imbalances.

Correct Answer: D

Rationale: The correct answer is D. Increased urinary output greater than fluid intake can indicate diabetes insipidus, a common complication after pituitary surgery. Diabetes insipidus is characterized by the excretion of a large volume of dilute urine, leading to dehydration and electrolyte imbalances. This finding requires immediate assessment and intervention. Choice A, a Glasgow scale score of 15, indicates normal neurological functioning. Choice B, blood drainage on dressing measuring 3 cm, may require monitoring but is not a priority over the potential complication of diabetes insipidus. Choice C, a report of dry mouth, is a common complaint postoperatively and can be managed with oral care measures.

Correct Answer: C

Rationale: The correct answer is C: Impaired liver function. Impaired liver function is a contraindication to the use of oral contraceptives because they are metabolized in the liver. Choices A, B, and D are incorrect. Thyroid disease, allergy to penicillin, and abnormal blood glucose levels are not contraindications to combined oral contraceptives.

Correct Answer: B

Rationale: Diminished deep tendon reflexes are a sign of magnesium toxicity. Magnesium sulfate can depress the central nervous system, leading to decreased reflexes. Respiratory rate of 12/min, urine output 40 mL/hr, and systolic blood pressure of 140 mm Hg are not specific findings of magnesium toxicity. Respiratory depression, oliguria, and hypotension are more concerning signs that require immediate attention.
