Fundamentals HESI
1. The nurse is teaching an elderly client how to use MDIs (multi-dose inhalers). The nurse is concerned that the client is unable to coordinate the release of the medication with the inhalation phase. What is the nurse's best recommendation to improve the delivery of the medication?
- A. Nebulized treatments for home care
- B. Adding a spacer device to the MDI canister
- C. Asking a family member to assist the client with the MDI
- D. Requesting a visiting nurse to follow the client at home
Correct answer: B
Rationale: Adding a spacer device to the MDI canister is the best recommendation in this scenario. The spacer device helps to improve coordination and medication delivery by allowing the client more time to inhale the medication effectively. Nebulized treatments for home care (Choice A) involve a different delivery method and are not directly related to improving coordination with MDIs. Asking a family member to assist (Choice C) may not address the core issue of coordination between releasing the medication and inhalation. Requesting a visiting nurse (Choice D) may not be necessary if the client can improve coordination with the spacer device.
2. The nurse is preparing to administer an intramuscular injection to a 6-month-old infant. Which site is most appropriate for this injection?
- A. Deltoid muscle
- B. Ventrogluteal muscle
- C. Dorsogluteal muscle
- D. Vastus lateralis muscle
Correct answer: D
Rationale: The vastus lateralis muscle is the preferred site for intramuscular injections in infants due to its size and safety. The deltoid muscle is typically used for adults and older children. The ventrogluteal muscle is more commonly used in toddlers and older children. The dorsogluteal muscle is not recommended for intramuscular injections in any age group due to its proximity to major nerves and blood vessels, which poses a risk of injury or sciatic nerve damage.
3. What is the most common cause of shock (hypoperfusion) in infants and children?
- A. infection
- B. cardiac failure
- C. accidental poisoning
- D. severe allergic reaction
Correct answer: A
Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.
4. What is the best initial action for the nurse to take with a manic depressive male client who becomes loud and verbally aggressive towards a nurse?
- A. Have the staff escort the client to his room.
- B. Tell the client that his behavior will be recorded in his record.
- C. Redirect the client by asking him to engage in a game with peers.
- D. Review the medication record for an antipsychotic drug.
Correct answer: C
Rationale: In dealing with a manic depressive client who is being verbally aggressive, the best initial action for the nurse is to redirect the client by engaging him in a more constructive activity, such as playing card games with peers. This approach can help de-escalate the situation, shift the client's focus positively, and provide a distraction from the current behavior. Having the staff escort the client to his room may escalate the situation further. Threatening to record the behavior in his record is not likely to be effective in managing the immediate situation. Reviewing the medication record for an antipsychotic drug is important but would not be the best initial action in this scenario when the client is being verbally aggressive.
5. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?
- A. Low oxygen levels are present in the blood.
- B. High levels of carbon dioxide have accumulated in the blood.
- C. Increased bicarbonate levels are causing alkalosis.
- D. Respiratory rate is increased, causing hyperventilation.
Correct answer: B
Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
