Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with multiple sclerosis reporting diplopia is to recommend alternating eye patches during the day. This strategy can help relieve diplopia (double vision) by allowing each eye to rest alternately, reducing eye strain. Encouraging the client to focus on a distant object (Choice A) is not an appropriate intervention for diplopia in this case. Applying a warm compress to the client's eyes (Choice B) and administering artificial tears (Choice D) are not effective interventions for diplopia associated with multiple sclerosis.

Correct Answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.

Correct Answer: D

Rationale: The correct statement to include in the teaching about amniocentesis is that the client should report if they experience any contractions after the procedure. This is crucial because contractions could indicate preterm labor or other complications following the amniocentesis. Choices A and B are incorrect as a full bladder is not required for the procedure, and magnesium sulfate is not typically given before an amniocentesis. Choice C is incorrect as the procedure usually takes about 20-30 minutes to complete.

Correct Answer: B

Rationale: The correct action the nurse should include in the plan of care for a client with Parkinson's disease at risk for aspiration is to instruct the client to tilt their head forward when swallowing. This action helps protect the airway and reduces the risk of aspiration in clients with impaired swallowing, which is common in Parkinson's disease. Encouraging the client to eat thin liquids (Choice A) can increase the risk of aspiration as they are harder to control during swallowing. Giving the client large pieces of food (Choice C) can also increase the risk of choking and aspiration. Having the client lie down after meals (Choice D) can further increase the risk of aspiration due to the potential for reflux. Therefore, the best action to prevent aspiration in this situation is to instruct the client to tilt their head forward when swallowing.

Correct Answer: B

Rationale: The correct instruction is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to settle in the lungs and maximize its effectiveness. Choice A is incorrect as inhaling quickly may lead to improper medication delivery. Choice C is wrong because taking a second puff immediately after the first without waiting for the prescribed interval may cause an overdose. Choice D is also incorrect as exhaling fully after using the inhaler may result in the medication being exhaled rather than absorbed by the lungs.
