Nursing Elites

1. A hospitalized toddler who is recovering from a sickle cell crisis holds a toy and says, 'Mine.' According to Erikson's theory of psychosocial development, this child's behavior is a demonstration of which developmental stage?

• A. Autonomy vs. Shame and Doubt
• B. Industry vs. Inferiority
• C. Initiative vs. Guilt
• D. Trust vs. Mistrust

Correct answer: A

Rationale: The toddler's behavior of asserting possession ('Mine') reflects a desire for independence, aligning with Erikson's stage of Autonomy vs. Shame and Doubt. This stage, typical for toddlers aged 1-3 years, focuses on developing a sense of control and independence. Choices B, C, and D are incorrect: Industry vs. Inferiority relates to middle childhood, Initiative vs. Guilt pertains to preschoolers, and Trust vs. Mistrust is associated with infancy.

2. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

3. A client is admitted with a diagnosis of myocardial infarction (MI). Which intervention is a priority during the acute phase?

• A. Administer morphine for pain relief
• B. Encourage the client to perform isometric exercises
• C. Position the client flat in bed
• D. Restrict fluid intake

Correct answer: A

Rationale: During the acute phase of a myocardial infarction (MI), the priority intervention is to administer morphine for pain relief. Morphine not only alleviates pain but also reduces myocardial oxygen demand, which is crucial in the management of MI. Encouraging the client to perform isometric exercises (choice B) can increase myocardial oxygen demand and should be avoided during the acute phase. Positioning the client flat in bed (choice C) may worsen symptoms by increasing venous return and workload on the heart. Restricting fluid intake (choice D) is not a priority intervention during the acute phase of MI; maintaining adequate hydration is important for organ perfusion.

4. A client with a history of peptic ulcer disease (PUD) is prescribed omeprazole (Prilosec). What is the primary action of this medication?

• A. Neutralizes stomach acid
• B. Reduces gastric acid production
• C. Forms a protective barrier over ulcers
• D. Increases gastric mucus production

Correct answer: B

Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.

5. A client with cirrhosis is experiencing pruritus. Which intervention should the nurse include in the care plan?

• A. Administer antihistamines as prescribed
• B. Apply alcohol-based lotions to the skin
• C. Encourage frequent baths with hot water
• D. Limit fluid intake

Correct answer: A

Rationale: The correct answer is A: Administer antihistamines as prescribed. Pruritus, or itching, is a common symptom in clients with cirrhosis. Antihistamines can help relieve itching by blocking the effects of histamine. Applying alcohol-based lotions (choice B) can further dry out the skin and exacerbate itching. Encouraging frequent baths with hot water (choice C) can also worsen pruritus by stripping the skin of natural oils. Limiting fluid intake (choice D) is not directly related to managing pruritus in cirrhosis.
