1. Four hours following surgical repair of a compound fracture of the right ulna, the nurse is unable to palpate the client's right radial pulse. Which action should the nurse take first?
- A. Notify the healthcare provider of the finding immediately.
- B. Complete a neurovascular assessment of the right hand.
- C. Elevate the client's right hand on one or two pillows.
- D. Measure the client's blood pressure and apical pulse rate.
Correct answer: B
Rationale: Completing a neurovascular assessment of the right hand is the priority in this situation. This assessment will help determine the circulation, sensation, and movement of the affected limb, ensuring there are no complications like compartment syndrome or impaired perfusion. Notifying the healthcare provider immediately (Choice A) might be necessary but should come after assessing the client's neurovascular status. Elevating the client's right hand (Choice C) can be helpful in some cases but should not precede a neurovascular assessment. Measuring the client's blood pressure and apical pulse rate (Choice D) is important but not the priority when assessing a potential vascular compromise in the limb.
2. What is an ideal goal of treatment set by the nurse in the care plan for a client diagnosed with chronic kidney disease (CKD) to reduce the risk of pulmonary edema?
- A. Maintaining oxygen saturation above 92%
- B. Absence of crackles and wheezes in lung sounds
- C. Maintaining a balanced intake and output
- D. Absence of shortness of breath at rest
Correct answer: C
Rationale: The ideal goal of treatment for a client with chronic kidney disease (CKD) to reduce the risk of pulmonary edema is to maintain a balanced intake and output. This helps in achieving optimal fluid balance, enabling the heart to eject blood effectively without increasing pressure in the left ventricle and pulmonary vessels. While maintaining oxygen saturation above 92% is important for adequate tissue oxygenation, the primary focus in this scenario is fluid balance. Absence of crackles and wheezes in lung sounds is important to assess for pulmonary status, but it is not the primary goal to prevent pulmonary edema specifically. Similarly, absence of shortness of breath at rest is a relevant goal, but the emphasis in CKD management is on fluid balance to prevent pulmonary complications.
3. A client recovering from a urologic procedure is being assessed by a nurse. Which assessment finding indicates an obstruction of urine flow?
- A. Severe pain
- B. Overflow incontinence
- C. Hypotension
- D. Blood-tinged urine
Correct answer: B
Rationale: The correct answer is 'B: Overflow incontinence.' The most common manifestation of urethral stricture after a urologic procedure is obstruction of urine flow. This obstruction can lead to overflow incontinence, which is the involuntary loss of urine when the bladder is distended. Severe pain is not typically associated with an obstruction of urine flow. Hypotension is unrelated to this issue. Blood-tinged urine is not a direct indication of an obstruction of urine flow but may indicate other conditions like trauma or infection.
4. What is the most common cause of coronary artery disease?
- A. Atherosclerosis.
- B. Hyperlipidemia.
- C. Diabetes.
- D. Smoking.
Correct answer: A
Rationale: The correct answer is Atherosclerosis. It is the primary cause of coronary artery disease, as it involves the buildup of plaque in the arteries, restricting blood flow to the heart. Hyperlipidemia (choice B) contributes to atherosclerosis by increasing cholesterol levels in the blood but is not the direct cause of coronary artery disease. Diabetes (choice C) can accelerate atherosclerosis due to high blood sugar levels, but it is not the most common cause. Smoking (choice D) is a significant risk factor for developing coronary artery disease but is not the primary cause.
5. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?
- A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
- B. A serum drug level greater than the MEC broadens the spectrum of the drug.
- C. A serum drug level greater than the MEC helps eradicate bacterial infections.
- D. A serum drug level greater than the MEC increases the therapeutic index.
Correct answer: C
Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.
