1. A client with chronic kidney disease is prescribed darbepoetin alfa. The nurse should monitor for which potential side effect?
- A. Hypertension
- B. Hypotension
- C. Hyperkalemia
- D. Hyperglycemia
Correct answer: A
Rationale: The correct answer is A: Hypertension. Darbepoetin alfa, used to treat anemia in chronic kidney disease, can lead to hypertension as a side effect. This medication stimulates red blood cell production, which can increase blood pressure. Monitoring blood pressure regularly is crucial to detect and manage this potential adverse effect. Choices B, C, and D are incorrect because hypotension, hyperkalemia, and hyperglycemia are not commonly associated with darbepoetin alfa therapy in chronic kidney disease.
2. In preparing a care plan for a client admitted with a diagnosis of Guillain-Barre syndrome, which nursing problem has the highest priority?
- A. Ineffective coping related to uncertainty of disease progression
- B. Imbalanced nutrition: less than body requirements related to impaired swallowing reflex
- C. Ineffective breathing pattern related to ascending paralysis
- D. Impaired physical mobility related to asymmetrical descending paralysis
Correct answer: C
Rationale: Ineffective breathing pattern is the highest priority nursing problem for a client with Guillain-Barre syndrome due to the potential risk of respiratory failure. As the paralysis ascends, it can affect the muscles needed for breathing, leading to respiratory compromise. Addressing this problem promptly is crucial to prevent respiratory distress and failure. Choices A, B, and D are also important nursing problems in Guillain-Barre syndrome, but ensuring effective breathing takes precedence over coping, nutrition, and mobility due to the immediate threat it poses to the client's life.
3. What class of laxative would the nurse recommend to a patient asking about the best way to prevent constipation?
- A. Stimulant laxatives
- B. Bulk-forming laxatives
- C. Emollient laxatives
- D. Hyperosmotic laxatives
Correct answer: B
Rationale: The correct answer is B: Bulk-forming laxatives. These laxatives are recommended to prevent constipation because they work by absorbing liquid in the intestines, forming a bulky, soft stool that is easier to pass. They are safe and considered the most natural option. Stimulant laxatives (choice A) work by promoting bowel movements through intestinal contractions and are more suitable for treating occasional constipation rather than preventing it. Emollient laxatives (choice C) soften the stool by increasing the incorporation of water into the feces and are more suitable for patients who need to avoid straining during defecation. Hyperosmotic laxatives (choice D) work by drawing water into the intestine through osmosis and are typically used for more severe cases of constipation, not for prevention.
4. The RN is preparing to administer a prescribed dose of haloperidol (Haldol) to a client with schizophrenia. The client begins to exhibit muscle rigidity, fever, and altered mental status. What action should the RN take first?
- A. Administer the haloperidol as prescribed.
- B. Monitor the client's vital signs closely.
- C. Hold the medication and notify the healthcare provider.
- D. Give the client an antipyretic for the fever.
Correct answer: C
Rationale: Muscle rigidity, fever, and altered mental status are symptoms of neuroleptic malignant syndrome (NMS), a potentially life-threatening reaction to antipsychotic medications. The RN should hold the medication and notify the healthcare provider immediately. Option A is incorrect because administering more of the medication can worsen the symptoms. Option B is not the first priority when the client is experiencing symptoms of NMS. Option D is incorrect as addressing the fever alone does not address the underlying issue of NMS caused by haloperidol.
5. A client with generalized anxiety disorder is being taught about buspirone (BuSpar) by a nurse. Which statement by the client indicates a need for further teaching?
- A. I should take this medication on an empty stomach.
- B. It may take several weeks before I feel better.
- C. This medication does not cause dependence.
- D. I can drink alcohol while taking this medication.
Correct answer: D
Rationale: The statement 'I can drink alcohol while taking this medication' (D) indicates a need for further teaching. Clients should avoid alcohol while taking buspirone because it can increase the risk of side effects such as dizziness and drowsiness. Choices A, B, and C are correct statements regarding buspirone and do not require further teaching.
