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: A

Rationale: The correct answer is A: Pain radiating to the left arm. This is a classic symptom of myocardial infarction and indicates possible heart involvement. Reporting this finding to the provider is crucial for prompt evaluation and intervention. Choices B, C, and D are incorrect. Pain relieved by rest, pain worsened with breathing, and pain relieved by antacids are not typical symptoms of myocardial infarction. These findings do not raise the same level of concern as pain radiating to the left arm and are less indicative of cardiac involvement.

Correct Answer: C

Rationale: When a nurse assesses a 1-hour postpartum client with a boggy uterus located 2 cm above the umbilicus, it indicates uterine atony. The first action the nurse should take is to massage the fundus. Fundal massage helps stimulate uterine contractions, which will reduce bleeding and prevent postpartum hemorrhage. Taking vital signs, assessing lochia, or administering an oxytocin IV bolus are important interventions but should come after addressing uterine atony through fundal massage.

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.

Correct Answer: C

Rationale: The correct answer is C. A serum creatinine level of 5 mg/dL is significantly elevated and indicates the need for hemodialysis to help filter waste products from the blood. Elevated creatinine levels suggest impaired kidney function and the inability to effectively filter waste from the body. Choices A, B, and D are within normal ranges and do not indicate the need for immediate hemodialysis in a client with chronic kidney disease.
