Nursing Elites

1. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?

• A. Administer the medication as ordered.
• B. Encourage the patient to drink more fluids.
• C. Hold the medication and request an order for serum BUN and creatinine.
• D. Request an order for serum electrolytes and administer the medication.

Correct answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

2. A client's urinalysis results show a urine osmolality of 1200 mOsm/L. What action should the nurse take?

• A. Encourage the client to drink more fluids.
• B. Contact the provider and recommend a low-sodium diet.
• C. Prepare to administer an intravenous diuretic.
• D. Obtain a suction device and implement seizure precautions.

Correct answer: A

Rationale: The correct action for the nurse to take when the client has a urine osmolality of 1200 mOsm/L, indicating dehydration, is to encourage the client to drink more fluids. Dehydration can lead to elevated urine osmolality, and increasing fluid intake can help rehydrate the client. A low-sodium diet is not the priority in this scenario as it would not directly address the dehydration indicated by the high urine osmolality. Administering an intravenous diuretic would further concentrate the urine, exacerbating the dehydration. Obtaining a suction device and implementing seizure precautions are not indicated based on the client's urine osmolality results and would not address the underlying issue of dehydration.

3. What is an expected outcome when a client is receiving an IV administration of furosemide?

• A. Increased blood pressure.
• B. Increased urine output.
• C. Decreased pain.
• D. Decreased premature ventricular contractions.

Correct answer: B

Rationale: The correct answer is B: Increased urine output. Furosemide is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the ascending loop of Henle in the kidneys, leading to increased urine production. This diuretic effect helps to reduce fluid volume in the body, making it an expected outcome when a client is receiving furosemide. Choice A, increased blood pressure, is incorrect because furosemide typically causes a decrease in blood pressure due to its diuretic effect. Choice C, decreased pain, and choice D, decreased premature ventricular contractions, are unrelated to the pharmacological action of furosemide.

4. Which of the following lipid abnormalities is a risk factor for the development of atherosclerosis and peripheral vascular disease?

• A. Low concentration of triglycerides.
• B. High levels of high-density lipoprotein (HDL) cholesterol.
• C. High levels of low-density lipoprotein (LDL) cholesterol.
• D. Low levels of LDL cholesterol.

Correct answer: C

Rationale: The correct answer is C: High levels of low-density lipoprotein (LDL) cholesterol. High levels of LDL cholesterol contribute to the development of atherosclerosis and peripheral vascular disease by being deposited in the blood vessel walls, leading to the formation of plaques that can obstruct blood flow. Choice A is incorrect as a low concentration of triglycerides is not typically associated with an increased risk of atherosclerosis or PVD. Choice B is incorrect as high levels of high-density lipoprotein (HDL) cholesterol are actually considered protective against atherosclerosis as it helps remove cholesterol from arteries. Choice D is incorrect as low levels of LDL cholesterol are not typically considered a risk factor for atherosclerosis or PVD.

5. A client with a chest tube attached to a closed drainage system has undergone a chest x-ray, which revealed that the affected lung is fully reexpanded. The nurse anticipates that the next assessment of the chest tube system will reveal:

• A. No fluctuation in the water seal chamber
• B. Continuous bubbling in the water seal chamber
• C. Increased drainage in the collection chamber
• D. Continuous gentle suction in the suction control chamber

Correct answer: A

Rationale: When the client's lung is fully reexpanded, the chest tube drainage system will no longer be actively draining, and there will be no fluctuation in the water seal chamber. Option B, continuous bubbling in the water seal chamber, indicates an air leak in the system, which is not expected when the lung is fully expanded. Option C, increased drainage in the collection chamber, would not be expected when the lung is reexpanded as there should be minimal to no drainage. Option D, continuous gentle suction in the suction control chamber, would not be appropriate when the lung is fully reexpanded and the chest tube is typically on a water seal system at this point to promote reexpansion and prevent air from entering the pleural space.
