Exam Cram NCLEX RN Practice Questions

1. The chain of infection includes the ________________.

A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
B. active natural, active artificial, passive natural, and passive artificial
C. opportunism, weakness, immunity, and colonization
D. intrinsic, extrinsic, internal, and external transmission

Correct answer: A

Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.

2. Which of the following types of antipsychotic medications is most likely to produce extrapyramidal effects?

A. Atypical antipsychotic drugs
B. First-generation antipsychotic drugs
C. Third-generation antipsychotic drugs
D. Dopamine system stabilizers

Correct answer: B

Rationale: The correct answer is first-generation antipsychotic drugs. These drugs are potent antagonists of D2, D3, and D4 receptors, making them effective in treating target symptoms but also leading to numerous extrapyramidal side effects due to the blockade of D2 receptors. Atypical or second-generation antipsychotic drugs, as mentioned in choice A, are relatively weak D2 blockers, which results in a lower incidence of extrapyramidal side effects. Third-generation antipsychotic drugs, as in choice C, and dopamine system stabilizers, as in choice D, are not typically associated with significant extrapyramidal effects compared to first-generation antipsychotics.

3. The client is being educated about depression by the nurse. Which statement by the client indicates that the teaching has been effective?

A. ''All elderly individuals experience depression occasionally.''
B. ''I'm relieved that I will improve within 2 or 3 days.''
C. ''I never realized depression could occur without a specific cause.''
D. ''Reducing stress in my life will alleviate the depression.''

Correct answer: C

Rationale: The correct answer, 'I never realized depression could occur without a specific cause,' demonstrates an understanding that depression can arise without a clear trigger, indicating effective teaching. Choice A is incorrect because not all elderly individuals experience depression, and this statement doesn't show understanding. Choice B is incorrect as it reflects a misconception about the quick resolution of depression. Choice D is incorrect as it oversimplifies the relationship between stress reduction and depression resolution.

4. In a clinic in a primarily African American community, a higher incidence of uncontrolled hypertension is noted in patients. To correct this health disparity, what should the nurse do first?

A. Initiate a regular home-visit program by clinic nurses.
B. Schedule teaching sessions about low-salt diets at community events.
C. Assess the perceptions of community members about the care at the clinic.
D. Obtain low-cost antihypertensive drugs using government grant funding.

Correct answer: C

Rationale: To address the higher incidence of uncontrolled hypertension in the primarily African American community, the nurse should first assess the perceptions of community members about the care at the clinic. Understanding the community's perspective can provide valuable insights into the reasons behind the health disparity. Initiating a regular home-visit program or scheduling teaching sessions about low-salt diets are important interventions but should come after gathering information on community perceptions. Obtaining low-cost antihypertensive drugs is not the initial priority; understanding community perspectives is crucial for developing effective interventions.

5. A nurse is caring for a client who is post-op day #1 after a total hip replacement. Although the client was alert with a normal affect in the morning, by lunchtime, the nurse notes the client is confused, has slurred speech, and is having trouble with her balance. Her blood glucose level is 48 mg/dl. What is the next action of the nurse?

A. Contact the physician immediately
B. Administer a bolus of 50 cc of D20W through the IV
C. Administer 10 units of regular insulin
D. Give the client 6 oz. of orange juice

Correct answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.
