Correct Answer: A

Rationale: The correct answer is A: Constricted pupils. Constricted pupils are a classic sign of opioid intoxication, including heroin. Opioids like heroin cause the pupils to constrict due to their effect on the autonomic nervous system. Dilated pupils, increased reflexes, and elevated blood pressure are not typically associated with opioid intoxication but may be seen with other substances or conditions.

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: B

Rationale: The correct answer is B: 'Monitor for diaphoresis.' Diaphoresis, which refers to excessive sweating, is a common symptom of hypoglycemia. It indicates a low blood sugar level and should prompt immediate treatment. Polyuria (excessive urination), abdominal pain, and thirst are not typically associated with hypoglycemia. Polyuria is more commonly linked to hyperglycemia, while abdominal pain and thirst are not specific symptoms of hypoglycemia.

Correct Answer: C

Rationale: A boggy uterus located 2 cm above the umbilicus suggests uterine atony, which is a common cause of postpartum hemorrhage. The initial intervention in this situation is to massage the fundus. Fundal massage helps the uterus contract, promoting hemostasis and preventing excessive bleeding. Taking vital signs or assessing lochia are important actions but are secondary to addressing uterine atony. Administering oxytocin IV bolus is often done after fundal massage to further enhance uterine contractions.

Correct Answer: C

Rationale: 1 cm of water in the water seal chamber is insufficient to ensure proper functioning of the chest tube. The water seal chamber typically requires a water level of 2 cm. Tidaling with spontaneous respirations (choice A) is an expected finding indicating proper functioning. Having the drainage collection chamber 1/3 full (choice B) is within the normal range. A suction chamber pressure of -20 cm H2O (choice D) is an appropriate level for chest tube drainage.
