NCLEX PN Exam Cram
1. If a client is suffering from thyroid storm, the PN can expect to find on assessment:
- A. tachycardia and hyperthermia.
- B. bradycardia and hypothermia.
- C. a large goiter.
- D. a calm, quiet client
Correct answer: A
Rationale: In thyroid storm, there is an excess of thyroxine, leading to symptoms such as tachycardia (rapid heart rate) and hyperthermia (increased body temperature). Atrial fibrillation and palpitations are also commonly observed. Choices B and C are more indicative of hypothyroidism, where the thyroid is underactive, leading to bradycardia (slow heart rate), hypothermia (decreased body temperature), and the development of a large goiter. Choice D, a calm, quiet client, is unlikely in a thyroid storm where the individual would typically present with symptoms of agitation and restlessness due to the hypermetabolic state.
2. High uric acid levels can develop in clients who are receiving chemotherapy. This can be caused by
- A. the kidneys' inability to excrete the drug metabolites.
- B. rapid cell catabolism.
- C. toxic effects of the prophylactic antibiotics given concurrently.
- D. the altered blood pH from the acidic nature of the drugs.
Correct answer: B
Rationale: The correct answer is 'rapid cell catabolism.' Chemotherapy leads to the destruction of cells, resulting in increased uric acid levels due to cell breakdown. Choice A is incorrect because the issue is not with the kidneys' ability to excrete the drug metabolites but rather with the cell breakdown. Choice C is incorrect as the question focuses on chemotherapy and its effects, not prophylactic antibiotics. Choice D is incorrect as the question pertains to the development of high uric acid levels, not altered blood pH from acidic drugs.
3. Why is it often necessary to draw a complete blood count and differential (CBC/differential) when a client is being treated with an antiepileptic drug (AED)?
- A. The hematocrit is adversely affected due to increased vascular volume.
- B. AEDs can lead to blood dyscrasia as a side effect.
- C. AEDs may cause aplastic anemia and megaloblastic anemia.
- D. Some AEDs induce white blood cell reduction.
Correct answer: B
Rationale: When a client is being treated with antiepileptic drugs (AEDs), it is essential to monitor for potential side effects on blood parameters. Some AEDs can lead to blood dyscrasia, which includes conditions like aplastic anemia and megaloblastic anemia. Therefore, drawing a complete blood count and differential helps in identifying these adverse effects early. Choices A, C, and D are incorrect because the primary concern when monitoring blood parameters in clients on AEDs is the risk of blood dyscrasia, not changes in hematocrit due to vascular volume, white blood cell reduction, or immune modulation.
4. Which type of cells secrete insulin?
- A. alpha cells
- B. beta cells
- C. CD4 cells
- D. helper cells
Correct answer: B
Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.
5. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?
- A. mycobacterium tuberculosis
- B. clostridium tetani
- C. staphylococcus aureus
- D. human immunodeficiency virus
Correct answer: C
Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.
