A nurse is caring for a client who is receiving furosemide. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Serum sodium.
- B. Serum glucose.
- C. Serum potassium.
- D. Serum calcium.
Correct Answer: C
Rationale: The correct answer is C: Serum potassium. Furosemide is a potassium-wasting diuretic, meaning it can lead to potassium loss in the body. Monitoring serum potassium levels is crucial to evaluate the effectiveness of furosemide and prevent hypokalemia. Options A, B, and D are incorrect because furosemide does not directly affect sodium, glucose, or calcium levels in the same way it impacts potassium levels.

A nurse is creating a plan of care for a newly admitted client who has obsessive-compulsive disorder. Which of the following interventions should the nurse take?
- A. Allow the client enough time to perform rituals
- B. Give the client autonomy in scheduling activities
- C. Discourage the client from exploring irrational fears
- D. Provide negative reinforcement for ritualistic behaviors
Correct Answer: A
Rationale: The correct intervention for a client with obsessive-compulsive disorder is to allow the client enough time to perform rituals. This helps manage anxiety and stress in individuals with OCD. Allowing time for rituals can provide a sense of control and reduce distress. Choice B, giving the client autonomy in scheduling activities, may not address the core symptoms of OCD related to rituals and compulsions. Choice C, discouraging the client from exploring irrational fears, goes against the principles of exposure therapy, which is a common treatment for OCD. Choice D, providing negative reinforcement for ritualistic behaviors, is not recommended as it can reinforce the behavior rather than help the client manage it.
A nurse is caring for a client who has chronic kidney disease and a serum potassium level of 6.5 mEq/L. Which of the following actions should the nurse take?
- A. Administer sodium bicarbonate
- B. Administer sodium polystyrene sulfonate
- C. Administer calcium gluconate
- D. Administer calcium carbonate
Correct Answer: B
Rationale: The correct action for the nurse to take is to administer sodium polystyrene sulfonate. This medication promotes potassium excretion and helps lower serum potassium levels in clients with hyperkalemia, which is indicated by a high potassium level. Sodium bicarbonate (choice A) is not used to treat hyperkalemia. Calcium gluconate (choice C) and calcium carbonate (choice D) are used to manage hyperkalemia by stabilizing cell membranes but are not the initial treatment choice for lowering potassium levels.
A nurse is caring for a client who is newly diagnosed with pancreatic cancer and has questions about the disease. To research, the nurse should identify which of the following electronic databases has the most comprehensive collection of nursing articles?
- A. MEDLINE
- B. CINAHL
- C. ProQuest
- D. Health Source
Correct Answer: B
Rationale: The correct answer is B, CINAHL. CINAHL is specifically dedicated to nursing and allied health literature, making it the most appropriate database for nursing articles and research. It provides a comprehensive collection of nursing-related articles, journals, and research studies, which are essential for evidence-based practice. MEDLINE, on the other hand, is a valuable resource for medical literature but is not as nursing-focused as CINAHL. ProQuest and Health Source cover a wider range of subjects beyond nursing, so they are not as comprehensive when it comes to nursing-specific articles and research. Therefore, for the nurse looking to access a database with a vast collection of nursing articles, CINAHL is the most suitable option.
A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?
- A. aPTT 75 seconds.
- B. INR 1.2.
- C. Hemoglobin 10 g/dL.
- D. Fibrinogen level 350 mg/dL.
Correct Answer: A
Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.
A nurse is assessing a client who has a history of urinary incontinence. Which of the following findings should the nurse report to the provider?
- A. Urine output of 50 mL in 2 hours
- B. Presence of an indwelling urinary catheter
- C. Frequent urination at night
- D. Dark-colored urine
Correct Answer: D
Rationale: The correct answer is D, dark-colored urine. Dark-colored urine can indicate various issues such as dehydration, liver problems, or blood in the urine, which could be concerning and require further evaluation by the provider. Choices A, B, and C are not necessarily findings that would need immediate reporting to the provider. A urine output of 50 mL in 2 hours might be low but could be influenced by various factors and might not always require immediate action. The presence of an indwelling urinary catheter is a known history and not a new finding. Frequent urination at night could be a symptom related to various conditions but may not be an urgent concern unless accompanied by other significant symptoms.
