The kidneys regulate acid-base balance by all of the following mechanisms except:
- A. Excreting hydrogen ions (H )
- B. Reabsorbing carbon dioxide into the
- C. Reabsorbing or excreting HCO into blood
- D. retaining hydrogen ions
Correct Answer: B
Rationale: Rationale: The correct answer is B because the kidneys do not reabsorb carbon dioxide to regulate acid-base balance. Carbon dioxide is mainly regulated by the lungs through respiration. The kidneys regulate acid-base balance by excreting hydrogen ions, reabsorbing or excreting bicarbonate (HCO3-) into the blood, and retaining or excreting hydrogen ions. Reabsorbing carbon dioxide is not a mechanism utilized by the kidneys for acid-base balance. Choices A, C, and D are correct mechanisms involved in acid-base balance regulation by the kidneys.

Which of the following guidelines should a nursing instructor provide to nursing students who are now responsible for assessing their clients?
- A. Assessment data should be collected continuously.
- B. Assess your client after receiving the nursing report and again before giving a report to the next shift.
- C. Assess your client at least hourly if vital signs are unstable, and every two hours if stable.
- D. Assessment data should be collected prior to the physician rounding on the unit.
Correct Answer: A
Rationale: The correct answer is A because assessment data should be collected continuously to ensure timely detection of any changes in the client's condition. This allows for prompt interventions and prevents complications. Choice B is incorrect as assessment should be ongoing and not limited to specific times. Choice C is incorrect as the frequency of assessment should be based on client needs, not a fixed schedule. Choice D is incorrect as assessments should not be limited to certain times but should be ongoing to provide comprehensive care.
Mr. Aurelio diagnosed with heart failure, was prescribed with a 2 gm sodium diet. which of the following foods would nurse Norma instruct him to restrict?
- A. whole wheat bread
- B. canned tomato juice
- C. beef tenderloin strips
- D. apples
Correct Answer: B
Rationale: The correct answer is B: canned tomato juice. Canned tomato juice is high in sodium content, which would not be suitable for a patient on a 2 gm sodium diet for heart failure. Sodium restriction is crucial in managing heart failure to reduce fluid retention and strain on the heart. Whole wheat bread, beef tenderloin strips, and apples are lower in sodium content compared to canned tomato juice, making them more appropriate choices for someone on a low-sodium diet.
A client is scheduled to receive methotrexate (Folex), 0.625 mg/kg P.O. daily, to treat malignant lymphoma. Before administering the drug, the nurse reviews the client’s medication history. Which of the following drugs might interact with methotrexate?
- A. digoxin (Lanoxin)
- B. Probenecid (Benemid)
- C. theophylline (Slo-Phyllin)
- D. Famotidine (Pepcid)
Correct Answer: B
Rationale: The correct answer is B: Probenecid (Benemid). Probenecid can increase methotrexate levels, leading to potential toxicity. Methotrexate is primarily eliminated by the kidneys, and Probenecid inhibits renal tubular secretion, causing methotrexate levels to rise. Digoxin (A), theophylline (C), and famotidine (D) do not have significant interactions with methotrexate. In summary, Probenecid is the correct answer as it can increase methotrexate levels through renal tubular secretion inhibition, while the other choices do not have a significant interaction with methotrexate.
Which of the ff symptoms is observed in the client with Right Sided Heart Failure?
- A. Dependent pitting edema
- B. Orthopnea
- C. Exertional dyspnea
- D. Hemoptysis CARING FOR CLIENTS UNDERGOING CARDIOVASCULAR SURGERY
Correct Answer: A
Rationale: Rationale: Right-sided heart failure leads to fluid backup in the body causing dependent pitting edema due to fluid accumulation in the lower extremities. Orthopnea and exertional dyspnea are typically seen in left-sided heart failure. Hemoptysis is associated with conditions like pulmonary embolism or lung cancer, not right-sided heart failure. Therefore, the correct answer is A as it directly correlates with the symptoms of right-sided heart failure.
The nurse is caring for a client who’s hypoglycemic. This client will have a blood glucose level:
- A. Below 70mg/dl
- B. Between 70 and 120mg/dl
- C. Between 120 and 180mg/dl
- D. Over 180mg/dl A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET P
Correct Answer: A
Rationale: The correct answer is A, below 70mg/dl, for a hypoglycemic client. Hypoglycemia is defined as low blood glucose levels, typically below 70mg/dl. Symptoms of hypoglycemia include confusion, sweating, shakiness, and palpitations. Treating hypoglycemia involves providing the client with a fast-acting source of glucose to raise their blood sugar levels quickly. Choices B, C, and D are incorrect as they indicate normal or elevated blood glucose levels, which are not characteristic of hypoglycemia. It is crucial for the nurse to recognize and promptly address hypoglycemia to prevent potential complications.
