A client is receiving methotrexate (Mexate), 12g/m2 IV to treat osteogenic carcinoma. During methotrexate therapy, the nurse expects the client to receive which other drug to protect normal cells?

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: A

Rationale: The correct answer is A: "Disturbed thought processes." This is the problem statement because it identifies the client's main issue, which is the disturbance in their thought processes. The "related to" part (B) indicates the cause, "Alzheimer's disease" (C) is the etiology, and "incoherent language" (D) is the evidence. By focusing on the problem statement, the nurse can develop appropriate interventions to address the client's disturbed thought processes.

Correct Answer: B

Rationale: The correct answer is B: Potato. Potatoes are high in potassium, which is essential for various bodily functions. Potatoes can help increase potassium intake in patients who require it. Bread, eggs, and cereal are not as rich in potassium as potatoes. Increasing intake of these foods won't provide the necessary boost in potassium levels needed for the patient.

Correct Answer: E

Rationale: The correct answer is missing from the choices provided. However, for a client with an immune system disorder, essential nursing actions include: E: Educate the client on the importance of maintaining a healthy lifestyle, avoiding exposure to infections, and adhering to prescribed medications. This is crucial for managing the immune system disorder effectively. Incorrect choices: A: Following agency guidelines is important but doesn't specifically address the client's immune system disorder. B: Reviewing drug references may be necessary but is not a priority in managing the immune system disorder. C: Advising the client on modifying the home environment is not directly related to managing the immune system disorder. D: Monitoring the client for depression is important but not specific to addressing the immune system disorder.

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: Step 1: Crowded living conditions do not directly increase the risk of lung cancer. Step 2: Passive smoke (choice A) and air pollution (choice C) contain carcinogens linked to lung cancer. Step 3: Diet low in fruits and vegetables (choice D) may lead to poor immune function, potentially impacting cancer risk. Step 4: In summary, crowded living conditions do not contribute to lung cancer risk compared to the other choices.

Correct Answer: A

Rationale: The correct answer is A: The sympathetic nervous system saves fluid in response to the stress of surgery. The sympathetic nervous system is responsible for the "fight or flight" response, which includes the conservation of fluids during stressful situations. Dark amber and concentrated urine indicates dehydration, which can be a result of the sympathetic nervous system conserving fluids. B: The sympathetic nervous system does not "diereses" (increase urination) in response to stress. C: The parasympathetic nervous system is not involved in fluid conservation during stress. D: The parasympathetic nervous system does not "diereses" fluid in response to stress.

Correct Answer: C

Rationale: The correct answer is C: Bacon. Bacon contains the highest kilocalorie among the given choices due to its high fat content. Fat provides 9 kilocalories per gram, while carbohydrates (like in bread and apple) provide 4 kilocalories per gram and protein (like in chicken) provides 4 kilocalories per gram. Bacon, being high in fat, has more kilocalories compared to the other choices. Summary: A: Apple - Low in fat, primarily consists of carbohydrates, hence lower in kilocalories. B: Chicken - Contains protein, lower in kilocalories compared to fat, hence not the highest kilocalorie choice. D: Bread - Mainly consists of carbohydrates, lower in kilocalories compared to fat, making it not the highest kilocalorie choice.

Correct Answer: A

Rationale: The correct answer is A. 1. Change in level of consciousness is crucial in assessing neurological status. 2. Tachypnea indicates possible respiratory distress or oxygenation issues. 3. Tachycardia may suggest a cardiovascular problem or inadequate perfusion. 4. Petechiae can be a sign of bleeding disorders or sepsis. Option B is incorrect because chest pain, diaphoresis, and nausea/vomiting are more indicative of a cardiac event rather than monitoring for J.E.'s signs and symptoms. Option C is incorrect because loss of consciousness, bradycardia, and leg pain do not align with the signs and symptoms to monitor for J.E. Option D is incorrect because bradycardia, chest pain, and oliguria are not as comprehensive as the signs and symptoms listed in option A for monitoring J.E.
