Correct Answer: D

Rationale: Intramuscular injections in the ventrogluteal site should be administered at a 90-degree angle. This angle ensures that the medication reaches the muscle tissue effectively. Angles less than 90 degrees can cause subcutaneous injection instead of intramuscular, leading to slower absorption of the medication. Angles greater than 90 degrees risk hitting bone or nerves, causing unnecessary pain or injury. Therefore, the correct angle for administering intramuscular injections in the ventrogluteal site is 90 degrees.

Correct Answer: A

Rationale: The correct answer is A: Anorexia and weakness. These symptoms are early indicators of potential digitalis toxicity. Anorexia refers to a loss of appetite, which can be a sign of toxicity, and weakness can indicate an issue with digoxin. Choices B, C, and D are incorrect. Hyperactivity and hunger, tachycardia and increased urination, as well as polyphagia and polydipsia are not typically associated with digitalis toxicity.

Correct Answer: B

Rationale: The correct answer is B. Albuterol is a rescue inhaler that should be used during asthma attacks to provide quick relief by opening the airways. Using it daily as a preventive measure is not recommended. Choice A is incorrect because a dry cough is not a common side effect of albuterol. Choice C is incorrect as albuterol does not need to be taken with food. Choice D is incorrect because albuterol is not meant to be used daily for asthma prevention.

Correct Answer: B

Rationale: The correct answer is deep tendon reflexes. Monitoring deep tendon reflexes is crucial to assess for magnesium toxicity during therapy for preeclampsia. Magnesium sulfate can lead to neuromuscular blockade, reflected by decreased or absent deep tendon reflexes. Assessing bowel sounds (choice A) is important for gastrointestinal function but is not directly related to magnesium sulfate therapy. Oxygen saturation (choice C) is vital for respiratory status but is not specifically linked to magnesium sulfate administration. Fluid balance (choice D) is essential but does not directly correlate with monitoring for complications of magnesium sulfate therapy in the context of preeclampsia.

Correct Answer: D

Rationale: The correct answer is D: Hearing acuity. Gentamicin is known to be ototoxic, which means it can cause damage to the auditory system leading to hearing loss. Monitoring hearing acuity is crucial to detect early signs of hearing impairment. Monitoring urinary output (choice A) is important for assessing kidney function but is not directly related to gentamicin's adverse effects. Monitoring serum glucose (choice B) and respiratory rate (choice C) are not specifically associated with gentamicin therapy.
