A diabetic client develops sinusitis and otitis media accompanied by a fever of 100.8○0 F (38.2○0 C). What effect may this have on his need for insulin?

Correct Answer: D

Rationale: The correct answer is D: It will increase the need for insulin. Infections like sinusitis and otitis media can lead to increased stress on the body, causing insulin resistance and higher blood sugar levels. This leads to an increased demand for insulin to regulate blood sugar levels effectively. Therefore, the diabetic client's need for insulin will likely increase in this scenario. Incorrect choices: A: It will have no effect - Incorrect because infections and fever can impact insulin requirements. B: It will cause wide fluctuations in the need for insulin - Incorrect as infections generally lead to increased insulin needs, not fluctuations. C: It will decrease the need for insulin - Incorrect as infections and fever typically increase insulin requirements due to increased stress on the body.

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: B

Rationale: The correct answer is B: Efferent. Efferent neurons transmit signals from the central nervous system to muscles and glands, controlling movement and secretion. Afferent neurons carry signals from sensory receptors to the central nervous system, not towards muscles or glands. "Affective" relates to emotions, not neural function. "Effective" does not describe the direction of signal transmission in the nervous system. Therefore, B is the correct choice.

Correct Answer:

Rationale: Correct Answer: A: The patient will ambulate in the hallway twice this shift using crutches correctly. Rationale: 1. This choice outlines a specific nursing intervention - ambulating with crutches. 2. It includes clear actions for the patient to ambulate and specifies using crutches correctly. 3. It addresses the patient's physical mobility needs actively. 4. It focuses on promoting independence and functional ability. Summary of other choices: B: This choice includes the nursing diagnosis and the plan but lacks the specificity of the correct answer. C: This choice includes the nursing diagnosis and specifies the use of crutches but lacks the clarity of correct implementation. D: This choice only identifies the patient's condition without providing a specific nursing intervention.

Correct Answer: C

Rationale: The correct answer is C: 2, 3, and 4. High cholesterol, cigarette smoking, and a sedentary lifestyle are modifiable risk factors for developing hypertension. High cholesterol can lead to atherosclerosis, increasing blood pressure. Smoking can constrict blood vessels, raising blood pressure. Sedentary lifestyle can lead to obesity and overall poor cardiovascular health, contributing to hypertension. Race and age are non-modifiable risk factors. Choice A is incorrect because it includes race, a non-modifiable factor. Choice B is incorrect because it includes age, which is also non-modifiable. Choice D is incorrect because it includes all factors, including non-modifiable ones.

Correct Answer: C

Rationale: The correct answer is C because decreased pulse rate and widened pulse pressure are not signs of hypovolemia. In hypovolemia, the body tries to compensate by increasing the heart rate and narrowing the pulse pressure to maintain adequate blood flow. A is incorrect as dry mucous membranes and soft eyeballs are signs of dehydration. B is incorrect as increased hematocrit and hemoglobin are indicators of hemoconcentration in hypovolemia. D is incorrect as increased lethargy and confusion can be seen in severe hypovolemia due to poor perfusion of vital organs.

Correct Answer: B

Rationale: Step 1: High cholesterol levels contribute to the buildup of plaque in arteries, leading to atherosclerosis and increasing the risk of coronary artery disease. Step 2: Atherosclerosis can result in a blockage of blood flow to the heart, causing a myocardial infarction (MI). Step 3: Age is a risk factor for CAD but not directly linked to MI development. Step 4: Medication usage may impact risk factors but is not a direct cause of MI. Step 5: Gender can influence risk but is not the primary factor in MI development.

Correct Answer: B

Rationale: The correct answer is B: All women over age 40 should have an annual mammogram. The American Cancer Society recommends annual mammograms starting at age 40 for women with an average risk of breast cancer. This is based on evidence showing that regular mammograms starting at age 40 help in early detection and improve outcomes. Choice A is incorrect because the recommended age is 40, not 30. Choice C is incorrect as it focuses only on family history, while screening guidelines are based on overall risk factors. Choice D is incorrect because feeling at risk alone is not a sufficient indication for annual mammograms without considering other risk factors.

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. Lung cancer causes the most deaths in women due to its high mortality rate. It is often diagnosed at an advanced stage, leading to poorer outcomes. Breast cancer, although common, has a lower mortality rate compared to lung cancer. Brain cancer is relatively rare in comparison. Colon and rectal cancer, while significant, do not surpass lung cancer in terms of causing the most deaths in women.
