Nursing Elites

1. Which of the following is not a primary function of the kidneys?

• A. blood pressure control
• B. vitamin D activation
• C. erythropoietin production
• D. reabsorption of waste products

Correct answer: D

Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.

2. A nurse reviews the health history of a client who will be seeing the health care provider to obtain a prescription for a combination oral contraceptive (estrogen and progestin). Which finding in the health history would cause the nurse to determine that the use of a combination oral contraceptive is contraindicated?

• A. The client has type 2 diabetes mellitus.
• B. The client is being treated for hypertension.
• C. The client has been treated for breast cancer.
• D. The client has hyperlipidemia.

Correct answer: C

Rationale: The correct answer is that the client has been treated for breast cancer. Combination oral contraceptives containing estrogen and progestin are contraindicated for women with a history of certain conditions, such as thrombophlebitis, thromboembolic disorders, cerebrovascular disease, coronary artery disease, myocardial infarction, known or suspected breast cancer, known or suspected estrogen-dependent neoplasm, benign or malignant liver tumors, and undiagnosed abnormal genital bleeding. Although having type 2 diabetes mellitus, being treated for hypertension, or having hyperlipidemia are risk factors that require caution when using combination oral contraceptives, they are not absolute contraindications like a history of breast cancer.

3. The client is preparing to learn about the effects of isoniazid (INH). Which information is essential for the client to understand?

• A. Isoniazid should be taken with meals to reduce gastrointestinal upset.
• B. Prolonged use of isoniazid may result in dark, concentrated urine.
• C. Taking aluminum hydroxide (Maalox) with isoniazid can enhance the drug's effects.
• D. Consuming alcohol daily can increase the risk of drug-induced hepatitis.

Correct answer: D

Rationale: It is crucial for the client to understand that consuming alcohol while on isoniazid can increase the risk of drug-induced hepatitis. Hepatic damage can lead to dark, concentrated urine. To minimize gastrointestinal upset, it is recommended to take isoniazid with meals rather than on an empty stomach. Additionally, the client should avoid taking aluminum-containing antacids like aluminum hydroxide with isoniazid, as it can reduce the drug's effectiveness. Choice A is incorrect because isoniazid should not be taken on an empty stomach to help reduce GI upset. Choice B is incorrect, as prolonged use of isoniazid does not typically cause dark, concentrated urine. Choice C is incorrect as taking aluminum hydroxide with isoniazid does not enhance the drug's effects; in fact, it may decrease its effectiveness.

4. Which of the following individuals is at the highest risk for suicide?

• A. 76-year-old widow with chronic renal failure
• B. 19-year-old with new SSRI therapy
• C. 28-year-old post-partum crying weekly
• D. 50-year-old client with obsessive-compulsive disorder (OCD) and depression

Correct answer: A

Rationale: The correct answer is the 76-year-old widow with chronic renal failure. Elderly individuals with chronic diseases, especially men, are at very high risk for suicide. The other choices, although they may be vulnerable populations, do not carry as high a risk for suicide. The 19-year-old with new SSRI therapy may actually have a lower risk as they are receiving treatment. The 28-year-old post-partum individual is experiencing a common emotional response after childbirth, which is not necessarily indicative of a high suicide risk. The 50-year-old with OCD and depression is at risk but not as high as elderly individuals with chronic illness.

5. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.
