Nursing Elites

1. The client with chronic renal failure who is on a low-sodium diet should avoid which of the following foods?

• A. Fresh fruits.
• B. Canned soups.
• C. Lean meats.
• D. Whole grain bread.

Correct answer: B

Rationale: Canned soups are high in sodium, which can lead to fluid retention and hypertension in clients with chronic renal failure who are on a low-sodium diet. Fresh fruits, lean meats, and whole grain bread are generally lower in sodium and can be included in a low-sodium diet. Lean meats provide essential protein, fresh fruits offer vitamins and minerals, and whole grain bread provides fiber, making them suitable choices for individuals with chronic renal failure.

2. A client has a long history of hypertension. Which category of medication would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?

• A. Antibiotic
• B. Histamine blocker
• C. Bronchodilator
• D. Angiotensin-converting enzyme (ACE) inhibitor

Correct answer: D

Rationale: The correct answer is D, Angiotensin-converting enzyme (ACE) inhibitor. ACE inhibitors inhibit the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking this conversion, ACE inhibitors promote vasodilation and improve perfusion to the kidneys. Additionally, ACE inhibitors block the breakdown of bradykinin and prostaglandin, further contributing to vasodilation. They also lead to increased renin and decreased aldosterone levels. These effects help in reducing blood pressure and protecting the kidneys in clients with hypertension. Antibiotics are used to fight infections, histamine blockers reduce inflammation, and bronchodilators widen the bronchi, none of which address the underlying processes involved in slowing the progression of chronic kidney disease (CKD) in hypertensive clients.

3. Which is a characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections?

• A. Sulfonamides are bactericidal.
• B. Sulfonamides are synthetic compounds.
• C. Sulfonamides have antifungal and antiviral properties.
• D. Sulfonamides increase bacterial synthesis of folic acid.

Correct answer: B

Rationale: The characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections is that sulfonamides are synthetic compounds, not derived from biologic substances. Choice A is incorrect because sulfonamides are bacteriostatic, not bactericidal. Choice C is incorrect because sulfonamides do not have antifungal and antiviral properties. Choice D is incorrect because sulfonamides act by inhibiting bacterial synthesis of folic acid, not increasing it.

4. 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.

5. A CD4+ lymphocyte count is performed on a client infected with HIV. The results of the test indicate a CD4+ count of 450 cells/L. The nurse interprets this test result as indicating:

• A. Improvement in the client
• B. The need for antiretroviral therapy
• C. The need to discontinue antiretroviral therapy
• D. An effective response to the treatment for HIV

Correct answer: B

Rationale: A CD4+ count of 450 cells/L is below the normal range (500-1600 cells/mcL), indicating a decline in immune function in the client. Antiretroviral therapy is recommended when the CD4+ count falls below 500 cells/mcL or below 25%, or when the client displays symptoms of HIV. Therefore, the interpretation of this test result suggests that the client requires antiretroviral therapy to manage the HIV infection. Choices A, C, and D are incorrect because a CD4+ count of 450 cells/L does not signify improvement, discontinuation of therapy, or an effective response to treatment for HIV.
