Nursing Elites

1. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

2. During a community health fair, a nurse is providing education on the effects of smoking. What is the most important information to include?

• A. Smoking can lead to cosmetic issues like tooth staining.
• B. Smoking is a leading cause of preventable death worldwide.
• C. Smoking temporarily elevates mood and alertness.
• D. Smoking is an expensive habit.

Correct answer: B

Rationale: The correct answer is B: 'Smoking is a leading cause of preventable death worldwide.' This information is crucial as it highlights the severe health risks associated with smoking, emphasizing the importance of cessation for overall health. Choice A is incorrect because cosmetic issues like tooth staining are not as significant as the life-threatening consequences of smoking. Choice C is incorrect because although smoking may temporarily elevate mood and alertness due to nicotine, this does not outweigh the serious health implications. Choice D is incorrect as while smoking is indeed an expensive habit, the focus should be on the health-related consequences to stress the urgency of quitting.

3. A client is being treated for dehydration. Which clinical finding would indicate that treatment is effective?

• A. Dry mucous membranes
• B. Increased urine output
• C. Tachycardia
• D. Hypotension

Correct answer: B

Rationale: The correct answer is B: Increased urine output. When a client is being treated for dehydration, increased urine output is a positive indication that the treatment is effective. This signifies that the body is beginning to rehydrate and eliminate excess fluid. Choices A, C, and D are incorrect because dry mucous membranes, tachycardia, and hypotension are all associated with dehydration and would not be signs of effective treatment.

4. A client with a diagnosis of heart failure is receiving furosemide (Lasix). Which electrolyte imbalance should the nurse monitor for?

• A. Hyperkalemia.
• B. Hyponatremia.
• C. Hypocalcemia.
• D. Hypokalemia.

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Therefore, the nurse should monitor the client for low potassium levels. Choice A, Hyperkalemia, is incorrect as furosemide does not typically cause high potassium levels. Choice B, Hyponatremia, is incorrect as furosemide primarily affects potassium levels, not sodium. Choice C, Hypocalcemia, is incorrect as furosemide does not directly impact calcium levels.

5. The client with diabetes is being taught about the importance of foot care. Which statement by the client indicates a need for further teaching?

• A. ''I will inspect my feet daily for any cuts or blisters.''
• B. ''I will soak my feet in warm water every day.''
• C. ''I will wear shoes that fit properly to avoid injury.''
• D. ''I will avoid walking barefoot to protect my feet.''

Correct answer: B

Rationale: Choice B is the correct answer because soaking feet daily can lead to skin breakdown, making it inappropriate for clients with diabetes. Inspecting feet daily for cuts or blisters (Choice A), wearing properly fitting shoes (Choice C), and avoiding walking barefoot (Choice D) are all appropriate measures to maintain foot health for clients with diabetes.
