Kaplan NCLEX Question of The Day
1. A client complaining of chest pain is prescribed an intravenous infusion of nitroglycerin (Nitro-Bid). After the infusion is initiated, the occurrence of which symptom warrants the nurse discontinuing an intravenous infusion of nitroglycerin?
- A. Frontal headache
- B. Orthostatic hypotension
- C. Decrease in intensity of chest pain
- D. Cool clammy skin
Correct answer: D
Rationale: The correct answer is 'Cool clammy skin.' This assessment finding indicates decreased cardiac output that could result from excessive vasodilation. Cool clammy skin is a sign of poor perfusion, suggesting that the blood pressure might be dropping too low. Discontinuing the nitroglycerin infusion is crucial to prevent further complications. Choice A, 'Frontal headache,' is a common side effect of nitroglycerin but not a reason to discontinue the infusion unless severe or persistent. Choice B, 'Orthostatic hypotension,' may occur as a side effect of nitroglycerin but does not necessarily warrant discontinuation unless severe. Choice C, 'Decrease in intensity of chest pain,' is actually an expected therapeutic response to nitroglycerin and indicates improved myocardial perfusion, so it is not a reason to stop the infusion.
2. Which microorganism is most commonly associated with gastritis?
- A. Syphilis
- B. Cytomegalovirus
- C. H. pylori
- D. Mycobacterium
Correct answer: C
Rationale: H. pylori is the most common microorganism associated with gastritis, present in over 80% of cases. While syphilis, cytomegalovirus, and mycobacterium can also cause gastritis, they are much less prevalent compared to H. pylori. Therefore, the correct answer is H. pylori.
3. What is pica?
- A. dependency on alcohol
- B. increased iron in the diet
- C. the sickle cell trait
- D. eating ice
Correct answer: D
Rationale: Pica is a disorder characterized by the ingestion of nonfood substances, which can lead to a clinical iron deficiency. It may be the first sign of an underlying issue. Individuals with pica consume a variety of nonfood items such as ice, clay, dirt, or paste. Choice A, dependency on alcohol, is incorrect as it is not related to pica. Choice B, increased iron in the diet, is incorrect because pica involves ingesting nonfood items rather than having an increased intake of iron. Choice C, the sickle cell trait, is unrelated to pica and is therefore incorrect.
4. The client has just returned from electroconvulsive therapy (ECT) and is very drowsy. What is the position of choice until the client regains full consciousness?
- A. Supine
- B. Fowlers
- C. Lateral
- D. High Fowlers
Correct answer: C
Rationale: The correct answer is 'Lateral.' When a client is very drowsy or sedated, placing them in the lateral position is important to maintain an open airway and allow for drainage of secretions. This position helps prevent airway obstruction and aspiration. Choice A, 'Supine,' is lying flat on the back and may not be ideal for a drowsy client due to the risk of airway compromise. Choice B, 'Fowlers,' is a semi-sitting position that is beneficial for clients with respiratory distress, but it may not be the best choice for a very drowsy individual. Choice D, 'High Fowlers,' is a more upright sitting position, which again may not be suitable for a drowsy client as it does not facilitate airway patency as effectively as the lateral position.
5. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:
- A. increased therapeutic effects of Drug A.
- B. increased adverse effects of Drug B.
- C. decreased therapeutic effects of Drug A.
- D. decreased therapeutic effects of Drug B.
Correct answer: C
Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.
