Correct Answer: C

Rationale: Administering insulin glargine at bedtime aligns with its long-acting profile, providing consistent basal insulin coverage over 24 hours for diabetes management.
Choice A is incorrect because rotating injection sites (e.g., abdomen, thighs) prevents lipodystrophy; using the same site each time is not recommended.
Choice B is incorrect because insulin glargine should not be shaken, as it is a clear solution, and shaking can denature the insulin.
Choice D is incorrect because insulin glargine is clear, not cloudy; cloudy insulin (e.g., NPH) requires mixing.

Correct Answer: D

Rationale: Monitoring for signs of liver dysfunction (e.g., jaundice, abdominal pain) is critical, as naltrexone, an opioid antagonist, can cause hepatotoxicity, requiring regular liver function tests.
Choice A is incorrect because naltrexone should not be started until the client is opioid-free for 7-10 days to avoid precipitating withdrawal.
Choice B is incorrect because naltrexone reduces cravings over time, not immediately.
Choice C is incorrect because naltrexone can be taken with or without food; a high-fat meal is not necessary.

Correct Answer: A

Rationale: Administering albuterol via nebulizer is the first action to take during an acute asthma attack, as it rapidly relaxes bronchial smooth muscles, relieving bronchospasm and improving airflow.
Choice B is incorrect because a supine position can worsen breathing; a semi-Fowler's or upright position is preferred to facilitate lung expansion.
Choice C is incorrect because obtaining a peak expiratory flow rate is useful for monitoring but is not the priority during an acute attack.
Choice D is incorrect because administering oxygen is secondary to bronchodilator therapy unless the client has severe hypoxia (e.g., oxygen saturation <90%).

Correct Answer: B

Rationale: Tremors and muscle stiffness are signs of extrapyramidal symptoms (EPS), a serious side effect of haloperidol, a typical antipsychotic, requiring immediate reporting for possible dose adjustment or antiparkinsonian medication.
Choice A is incorrect because dry mouth is a common, less severe side effect that can be managed with hydration or sugar-free gum.
Choice C is incorrect because weight loss is not typical; haloperidol may cause weight gain.
Choice D is incorrect because sedation is an expected side effect and does not require immediate reporting unless excessive.

Correct Answer: A

Rationale: Ear pain is a hallmark symptom of otitis media, caused by inflammation and pressure from fluid buildup in the middle ear.
Choice B is incorrect because clear ear drainage is not typical; purulent or bloody drainage may occur if the eardrum ruptures.
Choice C is incorrect because a fever of 37.2°C is not significant; otitis media often causes higher fevers (e.g., >38°
C) in acute cases.
Choice D is incorrect because otitis media typically causes hearing loss due to fluid in the middle ear, not improved hearing.
