1. A client with chronic renal failure is on a low-protein diet. Which of the following is the best response by the nurse when the client asks why this diet is necessary?
- A. It reduces the workload on your kidneys.
- B. It helps prevent the buildup of waste products.
- C. It helps maintain electrolyte balance in your body.
- D. It helps prevent dehydration.
Correct answer: B
Rationale: A low-protein diet is necessary for clients with chronic renal failure because it helps prevent the buildup of waste products, such as urea, in the body. Excess protein can lead to the accumulation of waste products that the compromised kidneys may not effectively filter out, further burdening the already impaired renal function. Choices A, C, and D are incorrect because the primary reason for a low-protein diet in chronic renal failure is to reduce the workload on the kidneys by minimizing the production of waste products that can exacerbate the condition, not specifically to reduce kidney workload, maintain electrolyte balance, or prevent dehydration.
2. The nurse is preparing to give trimethoprim-sulfamethoxazole (TMP-SMX) to a patient and notes a petechial rash on the patient’s extremities. The nurse will perform which action?
- A. Hold the dose and notify the provider.
- B. Request an order for a blood glucose level.
- C. Request an order for a BUN and creatinine level.
- D. Request an order for diphenhydramine (Benadryl).
Correct answer: A
Rationale: When a patient on TMP-SMX presents with a petechial rash, it can be indicative of a severe adverse reaction such as thrombocytopenia or a hypersensitivity reaction. The appropriate action for the nurse to take in this situation is to hold the dose of TMP-SMX and notify the healthcare provider immediately. This is crucial to prevent further administration of a medication that may be causing a serious adverse effect. Requesting a blood glucose level (Choice B) is not relevant in this scenario as the patient's presentation is suggestive of a skin-related issue rather than a glucose-related problem. Similarly, requesting a BUN and creatinine level (Choice C) would not address the immediate concern of a petechial rash and its association with TMP-SMX. Requesting an order for diphenhydramine (Choice D) may help manage itching or mild allergic reactions but is not the priority when a petechial rash is observed, as it may indicate a more severe reaction requiring immediate intervention.
3. After checking the urinary drainage system for kinks in the tubing, the nurse determines that a client who has returned from the post-anesthesia care has a dark, concentrated urinary output of 54 ml for the last 2 hours. What priority nursing action should be implemented?
- A. Report the findings to the surgeon.
- B. Irrigate the indwelling urinary catheter.
- C. Apply manual pressure to the bladder.
- D. Increase the IV flow rate for 15 minutes.
Correct answer: A
Rationale: In this situation, the nurse's priority action should be to report the findings to the surgeon. An adult should typically produce about 60 ml of urine per hour, so a dark, concentrated, and low urine output of 54 ml over 2 hours raises concerns. This change in urine output may indicate issues such as dehydration, renal problems, or inadequate fluid intake. Reporting this finding to the surgeon is crucial to ensure appropriate evaluation and intervention. Irrigating the catheter, applying manual pressure to the bladder, or increasing the IV flow rate are not appropriate actions based on the information provided and could potentially worsen the situation.
4. Which client should the nurse recognize as most likely to experience sleep apnea?
- A. Middle-aged female who takes a diuretic nightly.
- B. Obese older male client with a short, thick neck.
- C. Adolescent female with a history of tonsillectomy.
- D. School-aged male with a history of hyperactivity disorder.
Correct answer: B
Rationale: The correct answer is B. Sleep apnea is characterized by pauses in breathing during sleep, often due to a collapsed or blocked airway. Obesity and having a short, thick neck are risk factors for sleep apnea because excess fat around the neck can obstruct the airway. Option A (middle-aged female who takes a diuretic nightly) does not present as a common risk factor for sleep apnea. Option C (adolescent female with a history of tonsillectomy) may have had tonsils removed, which could reduce the risk of sleep apnea. Option D (school-aged male with a history of hyperactivity disorder) is not directly associated with an increased risk of sleep apnea.
5. A nurse is teaching a nursing student how to measure a carotid pulse. The nurse should tell the student to measure the pulse on only one side of the client’s neck primarily because:
- A. It is unnecessary to use both hands
- B. Feeling dual pulsations may lead to an incorrect measurement
- C. Palpating both carotid pulses simultaneously could occlude the trachea
- D. Palpating both carotid pulses simultaneously could cause the heart rate and blood pressure to drop
Correct answer: D
Rationale: The correct answer is D. Applying pressure to both carotid arteries at the same time is contraindicated. Excess pressure to the baroreceptors in the carotid vessels could cause the heart rate and blood pressure to reflexively drop. Palpating both carotid pulses simultaneously could also interfere with the flow of blood to the brain, possibly causing dizziness and syncope. Choices A, B, and C are incorrect. It is necessary to use both hands to measure the carotid pulse accurately. Feeling dual pulsations does not lead to an incorrect measurement, and palpating both carotid pulses simultaneously does not occlude the trachea.
