1. Why is a low-protein diet recommended for a client with hepatic encephalopathy?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Increased ammonia levels
- D. Electrolyte imbalance
Correct answer: C
Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.
2. After ingested food is mixed and churned with gastric secretions, the resulting semifluid mass is called:
- A. a bolus.
- B. chyme.
- C. rennin.
- D. glycogen.
Correct answer: B
Rationale: The correct answer is B: chyme. Chyme is the partially digested food that forms a semifluid mass after mixing with gastric juices. A is incorrect because a bolus refers to a rounded mass of food ready to be swallowed. C, rennin, is an enzyme involved in the digestion of milk proteins and not the term for the semifluid mass after food mixing with gastric secretions. D, glycogen, is a form of stored glucose in the body and is not the term used to describe the partially digested food mass in the stomach.
3. A home care nurse is following up with a postpartum client. Which of the following is a risk factor that places this client at risk for postpartum depression?
- A. History of anxiety
- B. Socioeconomic status
- C. Hormonal changes with a rapid decline in estrogen and progesterone
- D. Support from family members
Correct answer: C
Rationale: Postpartum depression can be triggered by various factors, but one of the strongest predictors is a rapid drop in estrogen and progesterone levels following childbirth. These hormonal changes can affect mood regulation, making some women more vulnerable to depression during the postpartum period. Choices A, B, and D are not direct risk factors associated with postpartum depression. While a history of anxiety may contribute, it is not as directly linked to the hormonal changes that occur postpartum. Socioeconomic status and support from family members may influence the overall well-being of the mother but are not specific risk factors for postpartum depression.
4. A nurse is caring for an older adult patient who is disoriented and has a history of falls. What actions should the nurse take?
- A. Place the bed in the lowest position, instruct the patient to remain in bed, ensure the bedside table is within reach.
- B. Instruct the patient to use the call light, apply an ambulation alarm to the patient’s leg, check on the patient hourly.
- C. Assign a sitter to monitor the patient, raise the bed rails, provide the patient with a call button.
- D. Check on the patient every two hours, provide verbal reminders to use the call light, lock the bed wheels.
Correct answer: B
Rationale: In this scenario, the correct actions for the nurse to take involve ensuring patient safety and fall prevention measures. Choice B is the correct answer because instructing the patient to use the call light allows them to signal for help, applying an ambulation alarm helps detect movement, and checking on the patient hourly increases monitoring frequency. These actions are essential for preventing falls in a disoriented patient with a history of falls. Choices A, C, and D are incorrect: A does not provide adequate monitoring or fall prevention measures, C relies solely on assigning a sitter without utilizing technological aids, and D lacks continuous monitoring and specific fall prevention strategies.
5. A healthcare provider is preparing to administer a scheduled dose of intravenous (IV) metoprolol (Lopressor) to a client. The client's apical pulse is 58 beats/minute. What action should the healthcare provider take?
- A. Administer the medication as prescribed.
- B. Hold the medication and notify the healthcare provider.
- C. Give half the prescribed dose and recheck the pulse in 30 minutes.
- D. Administer the medication and then recheck the pulse in 30 minutes.
Correct answer: B
Rationale: In the scenario described, with the client's apical pulse being 58 beats/minute, holding the medication and notifying the healthcare provider is the correct action. A low pulse rate may indicate bradycardia and may necessitate dose adjustment or further evaluation by the healthcare provider to prevent potential complications.
