Correct Answer: C

Rationale: The correct answer is C. Severe pain that is not relieved by analgesics may indicate neurovascular compromise or other complications and requires immediate attention by the provider. Choices A, B, and D are incorrect because clear fluid drainage from the pin sites is expected in skeletal traction, intermittent muscle spasms are common in this situation, and traction weights hanging freely indicate proper traction alignment.

Correct Answer: B

Rationale: To ensure proper functioning of a chest tube, the nurse should keep the drainage system below chest level. This position allows for proper drainage by gravity and prevents backflow into the pleural space. Clamping the chest tube intermittently can lead to a buildup of pressure and should be avoided. Emptying the drainage chamber every 4 hours is important but not directly related to maintaining the chest tube's function. Applying sterile gauze around the insertion site daily is essential for infection prevention but does not specifically ensure the proper functioning of the chest tube.

Correct Answer: B

Rationale: The correct instruction for a client prescribed ferrous sulfate is to take it with fluids other than coffee or tea. Coffee and tea can hinder iron absorption, so it's important to take the medication with other types of fluids. Choice A is incorrect because strawberries and citrus fruits are sources of vitamin C, which actually enhance iron absorption. Choice C is incorrect because ferrous sulfate is usually recommended to be taken on an empty stomach for better absorption. Choice D is incorrect as doubling the dose of ferrous sulfate can lead to an overdose and severe side effects.

Correct Answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. Magnesium sulfate toxicity can lead to diminished deep tendon reflexes, respiratory depression, and decreased urine output. Diminished deep tendon reflexes are an early sign of magnesium toxicity and indicate the need to discontinue the infusion. Elevated blood pressure (choice B) is not typically associated with magnesium toxicity. Increased urinary output (choice C) is also not a common finding in magnesium toxicity. Hyperreflexia (choice D) is not consistent with the expected findings of magnesium toxicity, which typically causes decreased reflexes.

Correct Answer: C

Rationale: The correct answer is C: Apical pulse. Digoxin's primary effect is to strengthen the force of the heart's contractions and slow the heart rate. Monitoring the apical pulse is crucial in evaluating the effectiveness of digoxin as it helps assess the medication's impact on the heart's function. Option A, respiratory rate, is not directly related to digoxin's mechanism of action and is not the most appropriate parameter to monitor for this medication. Option B, blood pressure, while important, may not be as sensitive as the apical pulse in assessing the effectiveness of digoxin. Option D, urine output, is more indicative of kidney function and fluid balance, rather than the direct effectiveness of digoxin in heart failure.
