When reconstituted, how many milligrams are in each milliliter of solution?
- A. 300 mg/mL
- B. 350 mg/mL
- C. 450 mg/mL
- D. 400 mg/mL
Correct Answer: D
Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.

A client with a diagnosis of osteoporosis is prescribed alendronate (Fosamax). What is the most important instruction the nurse should provide?
- A. Take the medication in the morning on an empty stomach.
- B. Take the medication at bedtime.
- C. Remain upright for at least 30 minutes after taking the medication.
- D. Take the medication with a full glass of water.
Correct Answer: D
Rationale: The most important instruction the nurse should provide to a client prescribed alendronate (Fosamax) for osteoporosis is to take the medication with a full glass of water. This is crucial to help prevent esophageal irritation. Option A is correct as alendronate should be taken in the morning on an empty stomach. Option C is incorrect because the client should remain upright for at least 30 minutes after taking the medication, not lie down. Option B is incorrect and a duplicate of Option A.
A client with a diagnosis of depression is prescribed an SSRI. What is the most important information the nurse should provide?
- A. Take the medication as prescribed.
- B. Avoid consuming grapefruit juice.
- C. Report any thoughts of self-harm immediately.
- D. Understand that improvement may take weeks.
Correct Answer: C
Rationale: The most important information the nurse should provide to a client prescribed an SSRI for depression is to report any thoughts of self-harm immediately. SSRIs can increase suicidal ideation, especially at the beginning of treatment, so it is crucial to monitor for this and take appropriate actions. While it is important to take the medication as prescribed (Choice A), the immediate need for reporting self-harm ideation takes precedence. Avoiding grapefruit juice (Choice B) is a general precaution with certain medications but not as critical in this scenario. Understanding that improvement may take weeks (Choice D) is important for managing treatment expectations, but ensuring the client's safety in the context of suicidal ideation is the top priority.
The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?
- A. Bilateral leg swelling.
- B. Sudden onset of chest pain.
- C. Gradual onset of dyspnea.
- D. Decreased breath sounds on auscultation.
Correct Answer: C
Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.
The nurse is teaching a client with hypertension about lifestyle modifications. Which recommendation is most effective for lowering blood pressure?
- A. Increase intake of red meat
- B. Engage in regular physical activity
- C. Consume a high-sodium diet
- D. Limit fluid intake to 1 liter per day
Correct Answer: B
Rationale: Engaging in regular physical activity is a highly effective recommendation for lowering blood pressure and improving overall cardiovascular health. Regular exercise helps to strengthen the heart, improve blood circulation, and manage weight, all of which contribute to reducing blood pressure levels. Choices A, C, and D are incorrect. Increasing intake of red meat can lead to higher saturated fat consumption, which is detrimental to heart health. Consuming a high-sodium diet can exacerbate hypertension by increasing blood pressure. Limiting fluid intake to 1 liter per day may lead to dehydration and is not a recommended approach for managing hypertension.
A client with asthma is prescribed a corticosteroid inhaler. What instruction should the nurse give about the inhaler?
- A. Use it only during asthma attacks
- B. Rinse the mouth after each use to prevent oral thrush
- C. It will provide immediate relief during an asthma attack
- D. Increase the dose if breathing does not improve
Correct Answer: B
Rationale: The correct instruction for a client using a corticosteroid inhaler is to rinse the mouth after each use to prevent the development of oral thrush, a common side effect of these inhalers. Choice A is incorrect as corticosteroid inhalers are often used regularly as a maintenance treatment, not just during asthma attacks. Choice C is incorrect because corticosteroid inhalers provide long-term control of asthma symptoms, not immediate relief during an attack. Choice D is incorrect and potentially dangerous advice as increasing the dose without medical guidance can lead to adverse effects.
