1. A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?

• A. U waves
• B. Absent P waves
• C. Elevated T waves
• D. Elevated ST segment

Correct answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

2. Albert, a 35-year-old insulin-dependent diabetic, is admitted to the hospital with a diagnosis of pneumonia. He has been febrile since admission. His daily insulin requirement is 24 units of NPH. Every morning Albert is given NPH insulin at 0730. Meals are served at 0830, 1230, and 1830. The nurse expects that the NPH insulin will reach its maximum effect (peak) between the hours of:

• A. 1130 and 1330.
• B. 1330 and 1930.
• C. 1530 and 2130.
• D. 1730 and 2330.

Correct answer: C

Rationale: NPH insulin typically peaks 4-12 hours after administration, so a peak between 1530 and 2130 would be expected. Choice A (1130 and 1330) is too early for the peak effect of NPH insulin. Choice B (1330 and 1930) falls within the possible peak period but is not as accurate as choice C. Choice D (1730 and 2330) is too late for the peak effect of NPH insulin based on the typical peak timing.

3. Which of the following actions could be considered a breach of patient confidentiality?

• A. Discussing patient information with other healthcare providers in a private setting.
• B. Sharing patient information with family members without the patient's consent.
• C. Discussing patient information in public areas where others may overhear.
• D. Sharing patient information in a private, secure setting with other healthcare providers involved in the patient's care.

Correct answer: C

Rationale: Discussing patient information in public areas where others may overhear is considered a breach of patient confidentiality because it compromises the privacy and confidentiality of the patient's health information. Choices A and D are not breaches of confidentiality as discussing patient information with other healthcare providers in a private setting or in a private, secure setting with those involved in the patient's care is appropriate. Choice B is also incorrect as sharing patient information with family members without the patient's consent could potentially be a breach of privacy but is not the best answer in this context.

4. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. Which of the following actions should the nurse take?

• A. Administer insulin
• B. Encourage increased fluid intake
• C. Monitor for signs of dehydration
• D. Check blood glucose levels

Correct answer: D

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of hyperglycemia, indicating high blood glucose levels. The priority action for the nurse is to check the client's blood glucose levels to assess the severity of hyperglycemia and determine the need for appropriate interventions. Administering insulin (Choice A) may be necessary based on the blood glucose levels but should only be done after confirming the current status. Encouraging increased fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. While monitoring for signs of dehydration (Choice C) is important in the long term, the immediate action should focus on determining the blood glucose levels first.

5. The healthcare professional is educating a client with Cushing's syndrome about dietary management. Which of the following instructions should the healthcare professional include?

• A. Increase sodium intake
• B. Limit protein intake
• C. Limit calcium intake
• D. Increase potassium intake

Correct answer: D

Rationale: For clients with Cushing's syndrome, they are at risk of developing hypokalemia due to increased excretion of potassium. Therefore, it is essential to advise them to increase their potassium intake. Choices A, B, and C are incorrect because: A) Increasing sodium intake can worsen fluid retention and hypertension common in Cushing's syndrome. B) Limiting protein intake is not necessary unless there are specific kidney issues that require protein restriction. C) Limiting calcium intake is not typically recommended unless there are underlying conditions such as hypercalcemia.
