1. Which of the following is a potassium-sparing diuretic?

• A. Furosemide
• B. Spironolactone
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

2. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

• A. Gram stain
• B. Culture
• C. Sensitivity
• D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.

3. What is a serious adverse reaction to penicillin?

• A. Liver Failure
• B. Anaphylaxis
• C. Respiratory Depression
• D. Edema

Correct answer: B

Rationale: The correct answer is B: Anaphylaxis. Anaphylaxis is a severe allergic reaction that can occur as a serious adverse reaction to penicillin. It is a life-threatening condition that requires immediate medical attention. Choices A, C, and D are incorrect. Liver failure is not a typical adverse reaction to penicillin, respiratory depression is more commonly associated with opioid medications, and edema is not a common severe adverse reaction to penicillin.

4. A client is taking Glipizide to treat Diabetes Mellitus. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of this medication?

• A. Cholesterol level.
• B. Hematocrit.
• C. Blood glucose level.
• D. Calcium level.

Correct answer: C

Rationale: The correct answer is C: Blood glucose level. Monitoring the client's blood glucose level is crucial when taking Glipizide, a medication used to lower blood glucose levels in individuals with Diabetes Mellitus. By monitoring the blood glucose level, the nurse can evaluate the effectiveness of the medication in managing the client's condition. Choices A, B, and D are incorrect as they are not directly related to assessing the effectiveness of Glipizide in treating Diabetes Mellitus. Cholesterol level, hematocrit, and calcium level may be important for other aspects of the client's health but are not the primary indicators of Glipizide's effectiveness.

5. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?

• A. PT
• B. INR
• C. aPTT
• D. Platelet count

Correct answer: C

Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
