Renal System Questions and Answers Questions
Question 1 of 5
What is the purpose of ANP in urine production?
Correct Answer: C
Rationale: ANP reduces sodium reabsorption, increasing urine output.
Question 2 of 5
If a urine specific gravity was measured to be 1.003, an interpretation would be that:
Correct Answer: B
Rationale: 1.003 SG suggests dilute urine, indicating hydration.
Question 3 of 5

Question 4 of 5
A client with chronic kidney disease (CKD) arrives at the emergency department reporting shortness of breath upon exertion. What should the nurse assess first?
Correct Answer: A
Rationale: In a client with chronic kidney disease (CKD) experiencing shortness of breath upon exertion, the nurse should first assess blood pressure. CKD often leads to fluid overload and hypertension due to impaired kidney function, which can exacerbate pulmonary edema and cause dyspnea. Elevated blood pressure can directly contribute to cardiac workload and respiratory distress, making it a critical initial assessment. While respiratory rate, oxygen saturation, and heart rate are also important, blood pressure provides immediate insight into the underlying cause and guides subsequent interventions, such as administering antihypertensive or diuretic therapy.
Question 5 of 5
A client is admitted with a deep and productive cough, hemoptysis, and a low-grade fever. The client's Mantoux skin test has a 15 mm induration. Which intervention should the nurse implement first?
Correct Answer: A
Rationale: The nurse should first initiate airborne particulate isolation precautions for a client with cough, hemoptysis, fever, and a 15 mm Mantoux test induration. These signs strongly suggest active tuberculosis (TB), a highly contagious airborne disease. Isolation prevents transmission to others, a public health priority, before confirmatory tests like sputum AFB or treatment with rifampin/isoniazid begin. A mask is insufficient alone, making immediate isolation the critical first step per infection control guidelines.
