Correct Answer: A

Rationale: The nurse should administer 0.2 mL of morphine sulfate. To calculate this, divide the desired dose (2 mg) by the concentration of the available solution (10 mg/mL). 2 mg / 10 mg/mL = 0.2 mL. Therefore, the nurse should administer 0.2 mL of morphine sulfate. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided concentration and desired dose.

Correct Answer: A

Rationale: The correct answer is A: Asthma. Clients with asthma should avoid Beta2 Blockade agents like propranolol as they can lead to bronchoconstriction, potentially worsening asthma symptoms. Choice B, hypertension, is not a contraindication for propranolol; in fact, it is commonly prescribed for hypertension. Choice C, tachydysrhythmias, is often an indication for propranolol due to its antiarrhythmic properties. Choice D, urolithiasis, does not directly impact the use of propranolol.

Correct Answer: D

Rationale: The nurse should combine both orders of insulin in the same syringe. To prepare the correct dose, the nurse should withdraw the regular insulin first (14 units) and then the NPH insulin (28 units), totaling 42 units. This combination ensures the client receives the prescribed doses of both types of insulin. Choices A, B, and C are incorrect because the nurse needs to prepare and administer both types of insulin as prescribed, resulting in a total of 42 units in the syringe.

Correct Answer: B

Rationale: The correct answer is deep tendon reflexes. Monitoring deep tendon reflexes is crucial to assess for magnesium toxicity during therapy for preeclampsia. Magnesium sulfate can lead to neuromuscular blockade, reflected by decreased or absent deep tendon reflexes. Assessing bowel sounds (choice A) is important for gastrointestinal function but is not directly related to magnesium sulfate therapy. Oxygen saturation (choice C) is vital for respiratory status but is not specifically linked to magnesium sulfate administration. Fluid balance (choice D) is essential but does not directly correlate with monitoring for complications of magnesium sulfate therapy in the context of preeclampsia.

Correct Answer: D

Rationale: The correct answer is D: Blood pressure. Before administering metoprolol, a beta-blocker commonly used to treat hypertension, the nurse should assess the client's blood pressure. Metoprolol works by lowering blood pressure and reducing the workload on the heart. Assessing the blood pressure is crucial to ensure it is within the acceptable range to administer the medication safely. Choices A, B, and C (Temperature, Heart rate, Respiratory rate) are important assessments in general patient care but are not specifically required before administering metoprolol for hypertension.
