The client is receiving heparin for thrombophlebitis of the left lower extremity. Which of the following drugs reverses the effects of heparin?

Correct Answer: B

Rationale: The correct answer is Protamine sulfate. Protamine sulfate is the antidote for heparin, as it reverses its effects. Cyanocobalamin is a form of Vitamin B12 and is not used to reverse heparin effects. Streptokinase is a thrombolytic agent that is used to dissolve blood clots, not to reverse heparin effects. Sodium warfarin is an anticoagulant, but it is not the antidote for heparin. Therefore, answers A, C, and D are incorrect as they do not reverse the effects of heparin.

Correct Answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.

Correct Answer: B

Rationale: A persistent cough might be related to an adverse reaction to captopril (Capoten). Tinnitus (choice A) and diarrhea (choice D) are not commonly associated adverse reactions of captopril. Muscle weakness (choice C) might occur initially but is not considered a common adverse effect of captopril. Therefore, the correct answer is B, persistent cough, as it is a known adverse reaction to captopril.

Correct Answer: C

Rationale: The correct answer is a red, beefy tongue, which is characteristic of pernicious anemia due to the atrophy of the papillae on the tongue. This finding is known as glossitis. A red, beefy tongue is a classic sign of pernicious anemia. Choice A, weight loss of 10 pounds in 2 weeks, is non-specific and not a typical finding in pernicious anemia. Choice B, complaints of numbness and tingling in the extremities, are more indicative of peripheral neuropathy, a common symptom of vitamin B12 deficiency, which can be seen in pernicious anemia. Choice D, a hemoglobin level of 12.0 g/dL, falls within the normal range and does not specifically point towards pernicious anemia, which is characterized by low hemoglobin levels due to impaired absorption of vitamin B12.

Correct Answer: A

Rationale: Proper application of nitroglycerin ointment involves rotating application sites to prevent skin irritation. It should be applied to the back and upper arms, not restricted to the chest, making option B incorrect. Rubbing it into the skin, as indicated in option C, is not recommended for nitroglycerin ointment as it can lead to faster absorption and potential side effects. The correct way is to cover it with a thin paper dressing, not gauze as mentioned in option D, to ensure proper absorption and prevent the medication from evaporating too quickly.
