HESI 799 RN Exit Exam Quizlet
1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?
- A. Low bioavailability
- B. Rapid onset of action
- C. Short half-life
- D. Narrow therapeutic index
Correct answer: D
Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
2. The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following interventions should the nurse implement?
- A. Encourage increased fluid intake
- B. Administer vasopressin
- C. Monitor for signs of dehydration
- D. Restrict oral fluids
Correct answer: D
Rationale: The correct intervention for a client with syndrome of inappropriate antidiuretic hormone (SIADH) is to restrict oral fluids. SIADH leads to excessive release of antidiuretic hormone (ADH), causing the body to retain water and diluting the sodium levels in the blood (hyponatremia). Restricting oral fluids helps prevent further water retention and worsening hyponatremia. Encouraging increased fluid intake (choice A) would exacerbate the problem by further diluting sodium levels. Administering vasopressin (choice B) is not indicated in SIADH, as the condition is characterized by excess ADH secretion. Monitoring for signs of dehydration (choice C) is not the priority in SIADH since the issue is water retention rather than dehydration.
3. A nurse is reinforcing teaching with a client who has cancer about foods that prevent protein-energy malnutrition. Which of the following foods should the nurse include in the teaching? (Select one that doesn't apply).
- A. Cottage cheese
- B. Milkshake
- C. Tuna fish
- D. Strawberries and bananas
Correct answer: D
Rationale: The correct answer is D - Strawberries and bananas. Cottage cheese, milkshakes, and tuna fish are high in protein and calories, making them beneficial in preventing protein-energy malnutrition. However, strawberries and bananas are not as protein or calorie-dense compared to the other options, so they are not as effective in preventing malnutrition.
4. The nurse is assessing a client with a history of schizophrenia who reports feeling sedated after starting a new antipsychotic medication. Which intervention is most appropriate?
- A. Reassure the client that sedation will subside with continued use
- B. Instruct the client to take the medication at bedtime
- C. Teach the client to take the medication with food
- D. Consult the healthcare provider to reduce the dosage
Correct answer: B
Rationale: Instructing the client to take the medication at bedtime is the most appropriate intervention. Taking antipsychotic medications at bedtime can help reduce the impact of sedation on the client's daily activities. This approach allows the client to sleep through the sedative effects. Choice A is incorrect because just reassuring the client may not address the immediate issue of sedation. Choice C is incorrect as taking the medication with food does not directly address the sedation concern. Choice D is not the first-line intervention; adjusting the dosage should be done by the healthcare provider after assessing the client's response to the medication.
5. An adult male is admitted to the psychiatric unit from the emergency department because he is in the manic disorder. He has lost 10 pounds in the last two weeks and has not bathed in a week because he has been 'trying to start a new business' and is 'too busy to eat.' He is alert and oriented to time, place and person, but not situation. Which nursing diagnosis has the greatest priority?
- A. Self-care deficit
- B. Disturbed sleep pattern
- C. Disturbed thought processes
- D. Imbalanced nutrition
Correct answer: D
Rationale: Imbalanced nutrition is the most critical nursing diagnosis to address in this scenario. The patient's significant weight loss and neglect of basic needs, such as eating and personal hygiene, indicate a severe imbalance in nutrition. Addressing this issue is crucial to prevent further health deterioration. Self-care deficit, disturbed sleep pattern, and disturbed thought processes are important but secondary concerns compared to the immediate risk posed by imbalanced nutrition. While self-care deficit and disturbed sleep pattern are valid concerns, the patient's weight loss and neglect of basic needs take precedence. Disturbed thought processes are also significant but addressing the imbalanced nutrition is more urgent in this context.
