Adult Health 2 Exam 1
1. 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.
2. A client with a diagnosis of anemia is being discharged with a prescription for ferrous sulfate. What should the nurse include in the teaching plan?
- A. Take the medication with milk to enhance absorption
- B. Expect stools to be dark in color
- C. Take the medication before bedtime
- D. Avoid foods high in vitamin C
Correct answer: B
Rationale: The correct answer is B: 'Expect stools to be dark in color.' Dark stools are a common side effect of iron supplementation due to the unabsorbed iron, and this is not a cause for concern. Choice A is incorrect because taking iron with milk can decrease its absorption due to calcium binding. Choice C is incorrect as there are no specific recommendations to take ferrous sulfate before bedtime. Choice D is also incorrect as vitamin C actually enhances iron absorption and should not be avoided.
3. 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.
4. The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?
- A. Muscle weakness
- B. Decreased deep tendon reflexes
- C. Constipation
- D. Hypotension
Correct answer: A
Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.
5. During a health screening, a client's blood pressure reads 160/100 mm Hg. What should the nurse recommend?
- A. Schedule a follow-up appointment
- B. Start making immediate dietary changes
- C. Begin an exercise program
- D. All of the above
Correct answer: A
Rationale: A follow-up with a healthcare provider is necessary to assess and manage the newly identified hypertension. While dietary changes and exercise are important for managing high blood pressure, immediate lifestyle modifications without further evaluation by a healthcare provider may not be safe or effective. Option A is the most appropriate initial step to ensure proper assessment and management of the client's blood pressure. Therefore, choices B and C are incorrect in this scenario. Option D is also incorrect because not all options should be implemented without proper medical guidance.
