Correct Answer: C

Rationale: The correct answer is C: 'This medication will decrease swelling and mucus production.' Montelukast is a leukotriene receptor antagonist that works by reducing swelling and mucus production in the airways, helping to manage asthma symptoms in the long term. Choices A, B, and D are incorrect because montelukast is not used for immediate relief during asthma attacks, pre-exercise prophylaxis, or short-term treatment; instead, it is taken regularly for asthma control.

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: A

Rationale: Using Naegele's rule, to calculate the expected delivery date, you add one year, subtract three months, and add seven days to the first day of the last menstrual period. If the last menstrual period was in October, adding one year gives October of the following year. Subtracting three months gives July, and adding seven days gives the expected delivery date of July 11th. Therefore, the correct answer is 711. Choice B (1011) is incorrect as it doesn't follow Naegele's rule calculations. Choices C (411) and D (1211) are also incorrect as they do not align with the correct application of Naegele's rule.

Correct Answer: D

Rationale: In chronic renal failure, it is essential to restrict protein intake to the Recommended Dietary Allowance (RDA) to reduce the accumulation of waste products that the kidneys can no longer effectively eliminate. Choices A, B, and C are incorrect because in chronic renal failure, high calcium, high potassium, and increased fluid intake can further strain the kidneys and worsen the condition.
