Adult Health 1 Exam 1
1. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). Which symptom should prompt the nurse to notify the healthcare provider?
- A. Weight gain.
- B. Bradycardia.
- C. Nervousness and tremors.
- D. Fatigue.
Correct answer: C
Rationale: The correct answer is C: 'Nervousness and tremors.' In a client with hypothyroidism prescribed levothyroxine, the development of nervousness and tremors may indicate hyperthyroidism, which can result from excessive dosing of levothyroxine. Therefore, the nurse should promptly notify the healthcare provider to adjust the medication dosage. Choices A, B, and D are incorrect because weight gain, bradycardia, and fatigue are more commonly associated with hypothyroidism itself, indicating that the levothyroxine therapy may not be effective enough, rather than being signs of excessive dosing.
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. The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?
- A. Bilateral leg swelling.
- B. Sudden onset of chest pain.
- C. Gradual onset of dyspnea.
- D. Decreased breath sounds on auscultation.
Correct answer: C
Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.
4. What are the final factors that contribute to blood pressure? (Select all that apply)
- A. Heart rate
- B. Stroke volume
- C. Peripheral resistance
- D. Neuroendocrine hormones
Correct answer: D
Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.
5. Which nonfood item is the most common cause of respiratory arrest in young children?
- A. Broken rattles
- B. Buttons
- C. Pacifiers
- D. Latex balloons
Correct answer: D
Rationale: The correct answer is D, Latex balloons. Latex balloons can pose a significant choking hazard to young children if inhaled, potentially leading to respiratory arrest. Broken rattles, buttons, and pacifiers are not typically known to cause respiratory arrest in young children. While these items can present choking hazards as well, the most common cause of respiratory arrest among young children is due to inhaling latex balloons.
