1. During a clinic visit for a sore throat, a client's basal metabolic panel reveals a serum potassium of 3.0 mEq/L. Which intervention should the PN recommend to the client based on this finding?
- A. Increase intake of dried peaches and apricots
- B. Reduce intake of red meats
- C. Encourage use of a soft toothbrush
- D. Force fluid intake to 1500 mL daily
Correct answer: A
Rationale: The correct answer is to recommend increasing the intake of dried peaches and apricots. A serum potassium level of 3.0 mEq/L is considered low. Increasing the intake of potassium-rich foods can help raise the serum potassium level, preventing complications such as muscle weakness and cardiac arrhythmias. Choice B, reducing intake of red meats, is incorrect because red meats are not specifically related to potassium levels. Choice C, encouraging the use of a soft toothbrush, is unrelated to addressing low potassium levels. Choice D, forcing fluid intake to 1500 mL daily, is not the appropriate intervention for low serum potassium; instead, increasing potassium-rich foods is more beneficial.
2. A new mother who is breastfeeding her newborn for the first time after delivery reports nipple pain when the baby sucks. Based on this client problem, which action should the PN take?
- A. Ensure that all the areolar tissue of the nipple is in the infant's mouth
- B. Have the mother reposition the infant from the cradle to the football hold
- C. Check for engorgement and assess the nipples for cracks or lesions
- D. Apply a warm compress to the breast for 10 minutes before each feeding
Correct answer: A
Rationale: Proper latch, including all the areolar tissue in the infant's mouth, is essential to prevent nipple pain and ensure effective breastfeeding. Option A is correct because ensuring that all the areolar tissue of the nipple is in the infant's mouth helps achieve a good latch, reducing nipple pain. Option B is incorrect as repositioning the infant may not address the root cause of the pain related to latch issues. Option C is incorrect because while checking for engorgement and nipple issues is important, it does not directly address the latch concern causing the pain. Option D is incorrect as applying a warm compress is not recommended for breastfeeding mothers; a warm compress can help with pain associated with engorgement, but it does not address latch issues.
3. The PN is caring for a client with schizophrenia who continues to repeat the last words heard. Which nursing problem should the PN document in the medical record?
- A. Altered thought processes
- B. Impaired social interaction
- C. Risk for self-directed violence
- D. Disturbed thought processes
Correct answer: D
Rationale: The correct answer is D: Disturbed thought processes. Echolalia, the repetition of heard words, is associated with disturbed thought processes, which are commonly seen in schizophrenia. Altered thought processes (Choice A) is a generic term and does not specifically address the behavior of repeating words. Impaired social interaction (Choice B) is not the primary concern when a client repeats the last words heard. Risk for self-directed violence (Choice C) is not directly related to the behavior of repeating words but focuses on the potential harm the client may cause to themselves.
4. For an older postoperative client with the nursing diagnosis 'impaired mobility related to fear of falling,' which desired outcome best directs the nurse's actions for the client?
- A. The client will ambulate with assistance every 4 hours
- B. The physical therapist will instruct the client in the use of a walker
- C. The client will use self-affirmation statements to decrease fear
- D. The nurse will place a gait belt on the client prior to ambulation
Correct answer: C
Rationale: Encouraging the client to use self-affirmation statements is the most appropriate desired outcome in this scenario. By utilizing self-affirmation statements, the client can address their fears directly and build confidence, which can ultimately lead to a reduction in fear of falling. While ambulating with assistance (choice A) is important, the focus here is on addressing the fear itself. Instructing the client in the use of a walker (choice B) and placing a gait belt on the client (choice D) are interventions that may be helpful but do not directly address the client's fear of falling.
5. What is the function of the enzyme lactase in the digestive system?
- A. Breaks down lactose into glucose and galactose
- B. Breaks down proteins into amino acids
- C. Converts starch into maltose
- D. Breaks down fats into fatty acids
Correct answer: A
Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.
