Saunders NCLEX RN Practice Questions

1. 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.

2. What is involved in obtaining informed consent?

A. An explanation of the reasons for the procedure
B. A signature on a form indicating the client agrees to the procedure
C. A statement affirming liability if complications arise during the procedure
D. Both A and C

Correct answer: A

Rationale: Informed consent involves providing the client with an explanation of the reasons for the procedure, the potential risks, benefits, and available alternatives. It is essential for the healthcare provider to ensure that the client understands the information provided before agreeing to the procedure. While obtaining a signature on a consent form is part of the process, it is not the sole indicator of informed consent. Option C, which mentions liability statements, is incorrect as informed consent focuses on ensuring the client understands the procedure, not on affirming liability. Therefore, the correct answer is the explanation of the reasons for the procedure.

3. The nurse is performing discharge teaching for Mrs. S after cardiac angioplasty. Her husband is present for the teaching. While explaining the prescription for antiplatelet medication to use at home, Mrs. S's husband states, 'I don't think I can afford to refill that medication.' What is the most appropriate response of the nurse?

A. Don't worry, your insurance will cover it.
B. I'll ask the physician if he can prescribe a medication that is more affordable.
C. You should apply for Medicare to see if they can help you.
D. This medication is essential for her care and should be given priority over all others that she is taking.

Correct answer: B

Rationale: The most appropriate response for the nurse in this situation is to offer assistance in exploring more affordable medication options. It is important to address the patient's concerns about medication costs to ensure adherence to the treatment plan. By suggesting to ask the physician if a more affordable alternative is available, the nurse shows understanding and a commitment to helping the patient access necessary medications. Choice A is incorrect because assuming insurance coverage without verifying can lead to false expectations. Choice C is incorrect as Medicare eligibility and assistance may not be applicable in this scenario. Choice D is incorrect as it does not address the financial concern raised by the husband and emphasizes the importance of the medication without offering a practical solution to affordability.

4. A 23-year-old patient in the 27th week of pregnancy has been hospitalized on complete bed rest for 6 days. She experiences sudden shortness of breath, accompanied by chest pain. Which of the following conditions is the most likely cause of her symptoms?

A. Myocardial infarction due to a history of atherosclerosis.
B. Pulmonary embolism due to deep vein thrombosis (DVT).
C. Anxiety attacks due to worries about her baby's health.
D. Congestive heart failure due to fluid overload.

Correct answer: B

Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.

5. A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?

A. Family history of heart disease
B. Overweight
C. Smoking
D. Age

Correct answer: A

Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.
