A couple tells a nurse that they are concerned about having children because there is bipolar disorder in first-degree relatives of each of them. What advice should the nurse give?

Correct Answer: B

Rationale: The correct answer is B: "Seek genetic counseling." This is the best advice because genetic counseling can help the couple understand the risk of passing on bipolar disorder to their children and explore options for family planning. Option A is too extreme and does not consider other factors. Option C is vague and does not provide any useful guidance. Option D is incorrect as bipolar disorder has a genetic component. Genetic counseling will provide the couple with the necessary information and support to make informed decisions about their family planning.

Correct Answer: D

Rationale: Step 1: Nitroglycerin is light-sensitive and can degrade when exposed to light. PVC plastic can release compounds that can interact with nitroglycerin. Therefore, non-PVC plastic must be used to prevent drug degradation. Step 2: Using non-PVC bags and tubing ensures the drug's stability and efficacy during administration, reducing the risk of adverse effects. Step 3: This requirement is specific to intravenous nitroglycerin administration and is crucial to ensure the patient receives the intended therapeutic benefits without compromising the drug's potency. In summary, choice D is correct because using non-PVC plastic intravenous bags and tubing is essential to maintain the stability and effectiveness of intravenous nitroglycerin. Choices A, B, and C are incorrect as they do not address the specific requirement related to the administration of this medication.

Correct Answer: C

Rationale: Rationale: 1. Patient C has coronary heart disease, indicating a higher risk of cardiovascular events. 2. The LDL level of 165 mg/dL is above the recommended target for patients with coronary heart disease. 3. Lowering cholesterol levels in patients with existing heart disease is crucial to reduce the risk of further complications. Summary: A: LDL level is within the recommended range for patients with coronary heart disease. B: LDL level is high, but the absence of coronary heart disease makes this patient less of a priority. D: Although the LDL level is optimal, having coronary heart disease takes precedence over the number of risk factors.

Correct Answer: B

Rationale: The correct answer is B: Increased activity tolerance. Iron supplements help increase red blood cell production, improving oxygen delivery to tissues and reducing fatigue. Increased activity tolerance is a common therapeutic response to iron supplementation. Decreased weight (A) is not a direct therapeutic response to iron supplementation. Decreased palpitations (C) may improve with increased iron levels, but it is not the primary expected outcome. Increased appetite (D) is not a typical response to iron supplementation and may not be directly related to improved anemia symptoms.

Correct Answer: C

Rationale: Systemic clearance (CLs) is related to the volume of distribution, half-life, and elimination rate constant. CLs represents the efficiency of elimination of a drug from the body and is calculated as the rate of drug elimination divided by the plasma concentration. The volume of distribution influences the initial concentration of the drug in the body, half-life determines the time taken for the drug concentration to decrease by half, and the elimination rate constant reflects the rate at which the drug is removed from the body. Therefore, these parameters directly impact systemic clearance. Choices A, B, and D do not encompass all the essential factors that contribute to systemic clearance, making them incorrect options.
