A nurse is caring for a male client who reports nausea and vomiting and is receiving IV fluid therapy. His blood urea nitrogen (BUN) is 32 mg/dL, creatinine 1.1 mg/dL, and hematocrit 50%. Which of the following nursing interventions is appropriate?
Continue routine care because the results are within the expected reference range.
Evaluate urine for amount and for specific gravity.
Collect a urine specimen for culture and sensitivity.
Decrease the IV fluid infusion rate and limit oral fluid intake.
The Correct Answer is B
Choice A Reason: This is incorrect because the results are not within the expected reference range. The client's BUN, creatinine, and hematocrit are elevated, indicating dehydration or reduced renal perfusion.
Choice B Reason: This is correct because evaluating urine for amount and for specific gravity can help assess the client's hydration status and renal function. These actions can help assess the client's hydration status and renal function, which may be affected by nausea and vomiting. The client's BUN, creatinine, and hematocrit are elevated, indicating dehydration or reduced renal perfusion. The normal ranges for BUN are 7 to 20 mg/dL, for creatinine are
0.6 to 1.2 mg/dL, and for hematocrit are 38% to 50% for males. The nurse should monitor the urine output and specific gravity, which reflect the concentration and volume of urine. The normal range for urine output is 30 to 60 mL/hour, and for specific gravity is 1.005 to 1.030.
Choice C Reason: This is incorrect because collecting a urine specimen for culture and sensitivity is not indicated for this client. This action is used to diagnose urinary tract infections, which are not suggested by the client's symptoms or results.
Choice D Reason: This is incorrect because decreasing the IV fluid infusion rate and limiting oral fluid intake can worsen the client's dehydration and renal perfusion. The nurse should maintain adequate fluid intake and balance to prevent further complications.

Correct Answer is D
Explanation
Choice a) is incorrect because elevating the client’s feet is not the priority action for a hypotensive client. Elevating the client’s feet may help increase the venous return to the heart, but it may also compromise the respiratory status of a client who has esophageal varices and is at risk of aspiration.
Choice b) is incorrect because administering a unit of packed RBCs is not the priority action for a hypotensive client. Administering a unit of packed RBCs may help increase the oxygen-carrying capacity of the blood, but it may also increase the blood viscosity and pressure, which can worsen the bleeding from the esophageal varices.
Choice c) is incorrect because initiating a dopamine IV infusion for the client is not the priority action for a hypotensive client. Initiating a dopamine IV infusion may help increase the blood pressure and cardiac output, but it may also cause vasoconstriction and tachycardia, which can increase the risk of hemorrhage and arrhythmias.
Choice d) is correct because increasing the client’s IV fluid rate is the priority action for a hypotensive client. Increasing the client’s IV fluid rate may help restore the intravascular volume and perfusion, which can prevent shock and organ damage. Increasing the client’s IV fluid rate may also dilute the blood and reduce its viscosity and pressure, which can decrease the bleeding from the esophageal varices.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because magnesium is not a medication for symptomatic bradycardia. Magnesium is a mineral that regulates muscle and nerve function, blood pressure, and blood sugar levels. Magnesium can be used to treat conditions such as torsades de pointes, eclampsia, or hypomagnesemia.
Choice B Reason: This is incorrect because sodium bicarbonate is not a medication for symptomatic bradycardia. Sodium bicarbonate is a substance that neutralizes acids and bases and regulates the pH of the blood. Sodium bicarbonate can be used to treat conditions such as metabolic acidosis, cardiac arrest, or overdose of certain drugs.
Choice C Reason: This is incorrect because epinephrine is not a medication for symptomatic bradycardia. Epinephrine is a hormone that activates the sympathetic nervous system and increases the heart rate, blood pressure, and blood flow to the muscles and brain. Epinephrine can be used to treat conditions such as anaphylaxis, cardiac arrest, or severe asthma.
Choice D Reason: This is correct because atropine is a medication for symptomatic bradycardia. Atropine blocks the action of the parasympathetic nervous system and increases the heart rate and conduction. Atropine is a medication that blocks the action of the parasympathetic nervous system and increases the heart rate and conduction.
Symptomatic bradycardia is a condition where the heart rate is slower than normal and causes symptoms such as dizziness, fatigue, chest pain, or fainting. Atropine can be used to treat symptomatic bradycardia by stimulating the sinoatrial node and the atrioventricular node, which are the natural pacemakers of the heart.
