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 client begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?
- A. Test all excreta for occult blood.
- B. Use a soft toothbrush or foam cleaner for oral hygiene.
- C. Implement reverse isolation.
- D. Avoid IM injections.
Correct answer: C
Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.
3. A pregnant Asian client who is experiencing morning sickness wants to take ginger to relieve the nausea. Which of the following responses by the nurse is appropriate?
- A. "I will call your physician to see if we can start some ginger."?
- B. "We don't use home remedies in this clinic."?
- C. "Herbs are not as effective as regular medicines."?
- D. "Just eat some dry crackers instead."?
Correct answer: A
Rationale: The correct response is appropriate as it demonstrates cultural sensitivity. Ginger is commonly used to alleviate nausea, particularly in Asian cultures. Contacting the physician to discuss the use of ginger ensures the client's safety and respects their preferences. Choices B and C are incorrect as they disregard the client's request and fail to acknowledge their cultural beliefs. Choice D is incorrect because it does not address the client's desire to use ginger for relief.
4. In alcoholics with anemia:
- A. Pernicious anemia is more common than folic acid deficiency.
- B. Iron deficiency and folic acid deficiency can coexist.
- C. The alcohol interferes with iron absorption.
- D. Oral vitamin replacement is contraindicated.
Correct answer: B
Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.
5. When teaching a client about anti-retroviral therapy for human immunodeficiency virus (HIV), the PN should emphasize:
- A. When started, therapy must not be interrupted to prevent viral resistance.
- B. When started, therapy must not be interrupted to prevent opportunistic infection.
- C. Therapy should not be interrupted for one day each month to prevent toxicity.
- D. Therapy should not be interrupted for one week every three months to prevent toxicity.
Correct answer: A
Rationale: When teaching a client about anti-retroviral therapy for HIV, it is crucial to emphasize that therapy must not be interrupted to prevent viral resistance. HIV mutates rapidly, and any interruption can lead to the emergence of resistant strains, compromising treatment effectiveness. Choice B is incorrect because keeping the virus in check with anti-retrovirals helps the client's immune system fight off opportunistic infections. Choices C and D are incorrect because therapy should not be interrupted for any reason. If toxicity occurs, the healthcare provider may adjust the treatment regimen by prescribing alternative anti-retroviral drugs.
