Nursing Elites

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

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

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. Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?

• A. Contractures.
• B. Constipation.
• C. Calcium loss.
• D. Catabolism.

Correct answer: C

Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.

3. A client on lithium has diarrhea and vomiting. What should the nurse do first?

• A. Recognize this as a drug interaction
• B. Give the client Cogentin
• C. Reassure the client that these are common side effects of lithium therapy
• D. Hold the next dose and obtain an order for a stat serum lithium level

Correct answer: D

Rationale: Diarrhea and vomiting are manifestations of lithium toxicity. The priority action for the nurse is to hold the next dose of lithium and obtain an order for a stat serum lithium level to confirm toxicity. This ensures patient safety and prevents further harm. Recognizing it as a drug interaction is not the first step in this scenario. Cogentin is used to manage extrapyramidal symptoms (EPS) associated with antipsychotics, not lithium toxicity. Reassuring the client about these symptoms as common side effects of lithium therapy is inappropriate as they indicate a more serious issue than typical side effects like hand tremors, nausea, polyuria, and polydipsia.

4. Family members of a patient ask repeated questions about the monitors and various readings in the patient's room. What is the most supportive response to their questions?

• A. Inform them that you can't take the time to answer all their questions
• B. Provide detailed explanations for each device
• C. Tell them it's too technical to explain
• D. Provide an overview and encourage them to spend their time with the patient

Correct answer: D

Rationale: Addressing the family's questions and providing an overview of information validates their concerns and addresses their requests. Limiting details and encouraging them to focus on the patient helps to avoid anxiety that could be created by focusing on values that should be interpreted in the context of the patient's situation by professionals with experience with such data. It also encourages them to provide what they uniquely have to offer: a comforting presence for their loved one. Choice A is dismissive and does not address the family's needs. Choice B may overwhelm the family with unnecessary technical information. Choice C is unhelpful as it disregards the family's genuine interest and concern. Therefore, choice D is the most appropriate response as it balances providing information while guiding the family to focus on supporting the patient.

5. Which is a physical, integumentary risk among the elderly population?

• A. Skin tears
• B. Thickened skin
• C. Thinning toe nails
• D. Less nasal hair

Correct answer: A

Rationale: Skin tears are a physical integumentary risk among the elderly population. As individuals age, their skin becomes thinner and more fragile, making them susceptible to skin tears. Thickened skin, thinning toenails, and reduced nasal hair are common age-related changes but do not pose the same level of risk as skin tears. Thickened skin may provide some protection, thinning toenails are primarily a cosmetic concern, and reduced nasal hair does not typically lead to significant health risks.
