Nursing Elites

1. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

2. 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.

3. A nurse reviews the laboratory findings of a client with a urinary tract infection. The laboratory report notes a “shift to the left” in the client’s white blood cell count. Which action should the nurse take?

• A. Request that the laboratory perform a differential analysis on the white blood cells.
• B. Notify the provider and start an intravenous line for parenteral antibiotics.
• C. Collaborate with the unlicensed assistive personnel (UAP) to strain the client’s urine for renal calculi.
• D. Assess the client for a potential allergic reaction and anaphylactic shock.

Correct answer: B

Rationale: A “shift to the left” in a white blood cell count indicates an increase in band cells, which is typically associated with urosepsis. In this scenario, the nurse should notify the provider and initiate IV antibiotics as a left shift is often seen in severe infections like urosepsis. Requesting a differential analysis on white blood cells would not be the immediate action needed in response to a left shift. Collaborating to strain urine for renal calculi is unrelated to the situation of a left shift in white blood cells due to urosepsis. Assessing for allergic reactions and anaphylactic shock is not the priority as a left shift is not indicative of an allergic response; it is associated with an increase in band cells, not eosinophils.

4. A nurse cares for adult clients who experience urge incontinence. For which client should the nurse plan a habit training program?

• A. A 78-year-old female who is confused
• B. A 65-year-old male with diabetes mellitus
• C. A 52-year-old female with kidney failure
• D. A 47-year-old male with arthritis

Correct answer: A

Rationale: For a bladder training program to succeed in a client with urge incontinence, the client must be alert, aware, and able to resist the urge to urinate. Habit training will work best for a confused client. This includes going to the bathroom (or being assisted to the bathroom) at set times. The other clients may benefit from other types of bladder training. A confused client may need structured assistance to establish a regular bathroom routine, which can help manage urge incontinence effectively. Clients with diabetes mellitus, kidney failure, or arthritis may require different strategies tailored to their specific conditions.

5. A client who underwent lobectomy 24 hours ago has not had any chest tube drainage for the past hour. What should the nurse do first?

• A. Contacts the physician
• B. Checks for kinks in the drainage system
• C. Checks the client’s blood pressure and heart rate
• D. Connects a new drainage system to the client’s chest tube

Correct answer: B

Rationale: When a chest tube is not draining, the nurse's initial action should be to check for kinks or clots in the chest drainage system. This step helps to ensure the patency of the system and allows for proper drainage. Checking the client's blood pressure and heart rate is important but not the priority when addressing a lack of chest tube drainage. Contacting the physician is warranted if signs of respiratory distress or mediastinal shift are observed after ruling out kinks or clots. Connecting a new drainage system is done when the fluid chamber is full, following a specific procedure to maintain a closed system and prevent complications.
