Insulin forces which of the following electrolytes out of the plasma and into the cells?
- A. Calcium
- B. Magnesium
- C. Phosphorus
- D. Potassium
Correct Answer: D
Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

Which atrioventricular heart block is also referred to as Mobitz II?
- A. Third-degree atrioventricular heart block
- B. Second-degree atrioventricular heart block
- C. First-degree atrioventricular heart block
- D. Complete heart block
Correct Answer: B
Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.
A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?
- A. Start oxygen at 2 L/min
- B. Initiate cardiac monitoring
- C. Initiate seizure precautions
- D. Keep the patient on bed rest
Correct Answer: B
Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.
Select a myth or falsehood relating to pain, pain management, and addiction.
- A. Addiction can be accurately predicted.
- B. Withdrawal, drug tolerance, and physical dependence do not indicate addiction.
- C. Pain medications should be avoided in patients with a substance abuse history.
- D. Addiction is signaled by deception and stockpiling by the client.
Correct Answer: A
Rationale: The correct answer is A because addiction cannot be accurately predicted. Choices B and C are incorrect. Withdrawal, drug tolerance, and physical dependence are not definitive signs of addiction, and pain medications can be used with patients who have a substance abuse history under careful monitoring. Choice D is incorrect because addiction is not solely signaled by deception and stockpiling; it is a complex condition with various behavioral, physical, and psychological aspects.
Round off these numbers to the nearest tenth:
- A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
- D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
Correct Answer: B
Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.
A client with DM states, 'I cannot eat big meals; I prefer to snack throughout the day.' The nurse should carefully explain that the:
- A. Regulated food intake is crucial for control
- B. Restricting salt and sugar is the main concern
- C. Opting for small, frequent meals aids digestion
- D. Consuming large meals can contribute to weight issues
Correct Answer: A
Rationale: In clients with diabetes, regulated food intake is crucial for controlling blood glucose levels. Choice A is the correct answer because maintaining consistent meal sizes and timings helps in managing blood sugar levels effectively. Choice B is incorrect because while monitoring salt and sugar intake is important, it is not the primary consideration in this scenario. Choice C is incorrect as the focus is on regulating food intake rather than aiding digestion. Choice D is also incorrect because consuming large meals can indeed lead to fluctuations in blood glucose levels, but the primary concern in this case is the regulation of food intake for better control of diabetes.
