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. What is the primary action a healthcare professional should take when a patient with a suspected myocardial infarction (MI) arrives in the emergency department?
- A. Apply a cold compress to the chest
- B. Administer oxygen and obtain an electrocardiogram (ECG)
- C. Encourage the patient to walk to reduce anxiety
- D. Provide a high-carbohydrate meal
Correct answer: B
Rationale: Administering oxygen and obtaining an ECG are crucial initial steps when managing a suspected myocardial infarction (MI). Oxygen helps improve oxygenation to the heart muscle, while an ECG is essential to diagnose an MI promptly. Applying a cold compress, encouraging the patient to walk, or providing a high-carbohydrate meal are not appropriate actions in the initial management of a suspected MI. Applying a cold compress can delay necessary interventions, encouraging the patient to walk may worsen the condition, and providing a high-carbohydrate meal is irrelevant to the immediate needs of a patient with a suspected MI.
3. The nurse is providing care for a client with type 1 diabetes mellitus who is receiving NPH insulin. The nurse notices that the client's evening glucose levels are consistently above 260 mg/dl. What does this indicate?
- A. States that her feet are constantly cold and feel numb
- B. A wound on the ankle that starts to drain and becomes painful
- C. Consecutive evening serum glucose greater than 260 mg/dl
- D. Reports nausea in the morning but still able to eat breakfast
Correct answer: C
Rationale: High evening glucose levels suggest that the current insulin dosage may be inadequate to control the client's blood sugar levels effectively. This indicates poor glycemic control and the need for a possible adjustment in the insulin regimen. Option A describes symptoms of peripheral neuropathy, which are not directly related to the elevated glucose levels but may be a long-term complication of diabetes. Option B describes a wound infection, which is not directly related to the client's high glucose levels. Option D mentions morning nausea, which could be due to various causes and is not directly related to the high evening glucose levels.
4. The single mother of a child with a head injury is sitting at the child's bedside crying when the PN enters the room. The mother states, 'Why did this happen to my child? I just can't cope with this.' How should the PN respond?
- A. Ask her to share how the injury occurred to her child.
- B. Recommend that she remain calm and positive for her child.
- C. Express that the present situation must be overwhelming.
- D. Determine if someone else can help her cope with this tragedy.
Correct answer: C
Rationale: Expressing empathy and acknowledging the mother's feelings helps in providing emotional support during a difficult time. This response validates her emotions and offers a comforting presence. Choice A is not appropriate as it focuses on gathering information rather than addressing the mother's emotional distress. Choice B may come off as dismissive of the mother's feelings and oversimplifies the complexity of the situation. Choice D shifts the responsibility to someone else instead of offering immediate support and comfort.
5. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?
- A. Parathyroid hormone
- B. Insulin
- C. Cortisol
- D. Thyroxine
Correct answer: A
Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.
