Fundamentals of Nursing Nursing Process Questions

Correct Answer: A

Rationale: The correct answer is A: Peripheral neuropathy. Didanosine (ddl) can cause peripheral neuropathy as a side effect, which can exacerbate existing neuropathy. The client's history of peripheral neuropathy warrants caution with this drug to prevent further nerve damage. Incorrect choices: B: Hypertension - Didanosine is not contraindicated in hypertension. C: Diabetes mellitus - While monitoring blood sugar levels is important, didanosine does not directly affect diabetes. D: Asthma - Didanosine does not have a significant impact on asthma. In summary, the client's pre-existing peripheral neuropathy makes it important to exercise caution with didanosine to avoid worsening this condition.

Correct Answer: D

Rationale: The correct answer is D: Leucovorin. Leucovorin is given during methotrexate therapy to protect normal cells by acting as a rescue agent that helps to reduce the toxic effects of methotrexate. It works by enhancing the efficacy of methotrexate in cancer cells while reducing its toxicity in normal cells. Probenecid (A) is not used to protect normal cells during methotrexate therapy. Cytarabine (B) and Thioguanine (C) are other chemotherapeutic agents and are not typically given to protect normal cells during methotrexate therapy.

Correct Answer: C

Rationale: The correct answer is C: Urine output increases. This indicates digoxin's effectiveness as it improves cardiac output by enhancing contraction strength. Increased urine output signifies improved kidney perfusion due to enhanced cardiac function. Option A is incorrect as decreased urine output indicates poor kidney perfusion. Option B is incorrect as digoxin aims to regulate heart rate, not necessarily make it higher than 95. Option D is incorrect as a heart rate lower than 50 could indicate digoxin toxicity.

Correct Answer: B

Rationale: The correct answer is B - Avoid traumatic injuries and exposure to any infection. For a client with pancytopenia caused by chemotherapy, their immune system is compromised, making them more susceptible to infections and bleeding. By avoiding traumatic injuries and exposure to infections, the client can reduce the risk of complications. Option A is incorrect because aggressive mouth care may further damage the already compromised oral mucosa. Option C is incorrect because excessive fluid intake may not be necessary and could worsen electrolyte imbalances. Option D is incorrect because muscle cramps and tingling sensations are not directly related to the main concern of infection and bleeding in pancytopenia.

Correct Answer: B

Rationale: The correct answer is B: Maintain strict aseptic technique. This is crucial during thoracentesis to prevent infection. Step 1: Before the procedure, sterile equipment and supplies must be used. Step 2: Proper hand hygiene is essential to reduce the risk of introducing pathogens. Step 3: During the procedure, maintaining a sterile field helps minimize the risk of contamination. Step 4: After the procedure, ensuring proper disposal of all used supplies prevents the spread of infection. Summary: A: Placing the patient in a quiet and cool room may be comforting but is not directly related to the safety of the procedure. C: Advising the patient to sit still is important for accurate needle insertion but does not address infection prevention. D: Applying pressure over the puncture site is important but does not prevent infection if aseptic technique is not maintained.
