The community mental health nurse is planning to visit four clients with schizophrenia today. Which client should the nurse see first?
- A. The mother who took her children from school because aliens were after them.
- B. The young man who has a history of substance abuse and no telephone.
- C. The newly diagnosed client who needs to be evaluated for medication compliance.
- D. The young woman who believes she is to blame for her recent miscarriage.
Correct Answer: A
Rationale: The correct answer is A: The mother who took her children from school because aliens were after them should be seen first. This choice indicates potential harm to the children due to the mother's delusions, posing an immediate safety concern. The nurse needs to assess the situation and ensure the children's safety. Choices B, C, and D do not present immediate safety risks. B is a history of substance abuse but no current immediate danger. C is newly diagnosed and can wait for evaluation, as can D who may need support but is not in immediate danger. Prioritizing safety is crucial in mental health nursing.

A patient with anemia is prescribed ferrous sulfate. What advice should the nurse give regarding the administration of this medication?
- A. Take with dairy products to increase absorption.
- B. Take on an empty stomach for best absorption.
- C. Avoid vitamin C while taking this medication.
- D. Take before bedtime.
Correct Answer: B
Rationale: The correct answer is B: Take on an empty stomach for best absorption. Ferrous sulfate is best absorbed on an empty stomach to maximize its effectiveness. When taken with food or dairy products (Choice A), the absorption of iron is reduced. Vitamin C actually enhances the absorption of iron, so avoiding it (Choice C) is not recommended. Taking the medication before bedtime (Choice D) may lead to gastrointestinal side effects and is not optimal for absorption.
A client with cirrhosis is at risk for bleeding. Which laboratory test is most important to monitor?
- A. Blood glucose
- B. Serum creatinine
- C. Prothrombin time (PT)
- D. Electrolytes
Correct Answer: C
Rationale: The correct answer is C: Prothrombin time (PT). In cirrhosis, the liver's ability to produce clotting factors is impaired, leading to a higher risk of bleeding. Monitoring PT helps assess the liver's synthetic function and the blood's ability to clot. Abnormal PT values indicate a higher bleeding risk and guide interventions like vitamin K or blood products. Blood glucose (A), serum creatinine (B), and electrolytes (D) do not directly reflect the liver's synthetic function or clotting status in cirrhosis, making them less relevant for monitoring bleeding risk.
A patient with a myocardial infarction (MI) is being treated with intravenous morphine. What is the primary reason for administering morphine to this patient?
- A. To reduce pain.
- B. To decrease anxiety.
- C. To reduce cardiac workload.
- D. To increase respiratory rate.
Correct Answer: C
Rationale: The primary reason for administering morphine to a patient with MI is to reduce cardiac workload. Morphine acts as a vasodilator and decreases preload and afterload on the heart, reducing myocardial oxygen demand. This helps to improve coronary blood flow and decrease the workload on the heart muscle, which is crucial in the setting of an MI.
Explanation for other choices:
A: While morphine can help reduce pain in MI, the primary reason for administering it is to reduce cardiac workload.
B: Morphine may have a calming effect, but the primary goal is to reduce cardiac workload.
D: Morphine can actually decrease respiratory rate as a side effect, making this choice incorrect.
A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?
- A. Stimulate white blood cell production
- B. Increase platelet count
- C. Promote red blood cell production
- D. Enhance clotting factor production
Correct Answer: C
Rationale: The correct answer is C: Promote red blood cell production. Erythropoietin is a hormone that stimulates the bone marrow to produce more red blood cells, helping to treat anemia. It does not stimulate white blood cell production (A), increase platelet count (B), or enhance clotting factor production (D). White blood cells are involved in the immune response, platelets are responsible for clotting, and clotting factors are proteins involved in the blood clotting process. Therefore, the primary action of erythropoietin is to specifically target red blood cell production to address anemia.
The patient has a calcium level of 12.1 mg/dL. Which nursing action should the nurse include on the care plan?
- A. Maintain the patient on bed rest.
- B. Auscultate lung sounds every 4 hours.
- C. Monitor for Trousseau's and Chvostek's signs.
- D. Encourage fluid intake up to 4000 mL every day.
Correct Answer: D
Rationale: The correct answer is D: Encourage fluid intake up to 4000 mL every day. High calcium levels can lead to dehydration, so encouraging fluid intake helps prevent this complication. Increased fluid intake also promotes calcium excretion through urine. Bed rest (A) is not directly related to managing high calcium levels. Auscultating lung sounds (B) every 4 hours is more relevant for respiratory issues. Monitoring for Trousseau's and Chvostek's signs (C) is associated with low calcium levels, not high levels.
