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. Rachel is a 48-year-old mother of three who has been admitted after a drug overdose in a failed suicide attempt. When she regains consciousness, she states that she is ashamed and embarrassed that she tried to take her own life. What is the most therapeutic response to Rachel's statement?

A. It's a relief your children weren't left without a mother.
B. What were you thinking?
C. We're here to help patients who value life.
D. I know life can be difficult. We're here to help you.

Correct answer: D

Rationale: The most therapeutic response to Rachel's statement is to provide non-judgmental support and hope. By acknowledging the patient's feelings of shame and embarrassment and offering help and understanding, the nurse can help Rachel maintain her self-esteem. Choice A is not therapeutic as it may unintentionally convey guilt or further shame. Choice B is judgmental and confrontational, which can create a barrier to open communication. Choice C is dismissive and does not address Rachel's emotional state. The correct response (Choice D) acknowledges the patient's struggle, offers support, and conveys empathy, aligning with the nurse's role to treat all patients with respect and dignity in challenging situations.

3. The clinic nurse teaches a patient with a 42 pack-year history of cigarette smoking about lung disease. Which information will be most important for the nurse to include?

A. Options for smoking cessation
B. Reasons for annual sputum cytology testing
C. Erlotinib (Tarceva) therapy to prevent tumor risk
D. Computed tomography (CT) screening for lung cancer

Correct answer: A

Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.

4. Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?

A. Kussmaul respirations
B. Cheyne-Stokes respirations
C. Biot's respirations
D. Cluster breathing

Correct answer: A

Rationale: Mr. N is most likely exhibiting Kussmaul respirations. Kussmaul respirations are a form of hyperventilation associated with conditions like metabolic acidosis. They are characterized by rapid, regular, and deep breathing. This type of respiratory pattern helps the body compensate for metabolic acidosis by attempting to blow off excess carbon dioxide. This pattern is different from Cheyne-Stokes respirations (choice B), which are characterized by alternating periods of deep, rapid breathing followed by apnea. Biot's respirations (choice C) are characterized by groups of quick, shallow inspirations followed by irregular periods of apnea, and Cluster breathing (choice D) involves clusters of breaths followed by periods of apnea, often seen in patients with brain injury or neurological conditions.

5. Plantar flexion can be prevented with ________________.

A. foot soaks
B. foot boards
C. toenail care
D. proper shoes

Correct answer: B

Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.
