1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. You are caring for a group of elderly clients, many of whom are affected by multiple chronic disorders and are also, at times, affected by some acute disorders that require medical and nursing attention. As you are caring for these clients, some will need a new medication regimen for an acute disorder. You should consider the fact that the elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to the elderly having a(n):

Correct answer: C

Rationale: The correct answer is 'Decreased hepatic metabolism.' The elderly population is at risk for more side effects, adverse drug reactions, and toxicity due to a decrease in hepatic metabolism. This is caused by changes in hepatic functioning in the elderly, including decreased hepatic blood flow and functioning. Choice A, 'Increased creatinine clearance,' is incorrect as aging typically results in decreased, not increased, creatinine clearance. Choice B, 'Impaired immune system,' is not directly related to the increased risk of adverse drug reactions in the elderly. Choice D, 'Increased bodily fat,' is not a primary factor contributing to the increased risk of medication-related issues in the elderly population.

3. What kind of preventive measures is MOST likely to be used to prevent Mary Eden from falling due to her muscular frailty?

Correct answer: A

Rationale: Mary Eden, due to her muscular frailty, is at risk of falling. The most effective preventive measure in this case would be physical therapy focusing on muscle strengthening exercises. Strengthening exercises can help improve her muscle tone and stability, reducing the risk of falls. While range of motion exercises may be beneficial, they may not directly address her muscular frailty and stability concerns as effectively as muscle strengthening exercises. Occupational therapy aims to help individuals with activities of daily living and functional tasks, not confusion. Medications to induce more sleep can actually increase the risk of falls due to potential side effects like dizziness or disorientation, rather than preventing falls.

4. A 23-year-old patient in the 27th week of pregnancy has been hospitalized on complete bed rest for 6 days. She experiences sudden shortness of breath, accompanied by chest pain. Which of the following conditions is the most likely cause of her symptoms?

Correct answer: B

Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.

5. What question must the nurse ask when formulating a nursing diagnosis?

Correct answer: B

Rationale: When formulating a nursing diagnosis, the nurse should focus on identifying the client's specific health problems that can be addressed through nursing interventions. The correct answer emphasizes the nurse's role in identifying and addressing client-specific issues through nursing care. Choice A is incorrect because nursing diagnoses are distinct from medical diagnoses made by physicians. Choice C is incorrect as it focuses on physician orders rather than the nurse's role in diagnosing and addressing client problems. Choice D is incorrect because it pertains to identifying underlying diseases, which is not the primary focus of nursing diagnoses.
