Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to share any additional information they may have forgotten or overlooked, ensuring a thorough health history interview. Choice A is incorrect as it implies the interviewer is unprepared or disinterested. Choice C is inappropriate as it may make the patient feel guilty or inadequate. Choice D is incorrect as it does not address the possibility of gathering more relevant information from the patient.

Correct Answer: B

Rationale: The correct answer is B: Keep extremities at neutral position. This intervention promotes proper blood flow and reduces the risk of thrombophlebitis by preventing compression or restriction of blood vessels. Removing and reapplying elastic stockings (choice A) can disrupt circulation and increase the risk of thrombophlebitis. Changing the client's position (choice C) may not directly address hemostasis or thrombophlebitis. Using a flotation mattress (choice D) is not specifically focused on maintaining proper positioning of the extremities to promote circulation.

Correct Answer: A

Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.

Correct Answer: A

Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.

Correct Answer: A

Rationale: Rationale: A: Diphenhydramine hydrochloride (Benadryl) is an antihistamine commonly used to treat allergic reactions, including those from bee stings. It can help alleviate symptoms like itching and swelling. Keeping Benadryl on hand is crucial for managing an allergic reaction promptly. Other Choices: B: Guaifenesin (Robitussin) is an expectorant used to treat coughs, not allergic reactions. C: Pseudoephedrine hydrochloride (Sudafed) is a decongestant used for nasal congestion, not allergic reactions. D: Loperamide (Imodium) is an antidiarrheal used to treat diarrhea, not allergic reactions.
