HESI PN Exit Exam 2023
1. A dispersion consists of a solute dispersed through a dispersing vehicle. Which of the following dispersions is a liquid for topical application that contains insoluble solids or liquids?
- A. Ointment
- B. Lotion
- C. Paste
- D. Gel
Correct answer: B
Rationale: The correct answer is B, 'Lotion.' A lotion is a liquid dispersion that contains insoluble solids or liquids for topical application. Ointments are more semi-solid and occlusive, pastes are thicker and contain higher concentrations of solids, and gels have a jelly-like consistency due to their three-dimensional network structure. Therefore, among the options, a lotion is the most suitable choice for containing insoluble solids or liquids for topical application.
2. A nurse in an outpatient clinic is caring for a client who has a new prescription for an antihypertensive medication. Which of the following instructions should the nurse give the client?
- A. “Get up and change positions slowly.”
- B. “Avoid eating aged cheese and smoked meat.”
- C. “Report any unusual bruising or bleeding to the doctor immediately.”
- D. “Eat the same amount of foods that contain vitamin K every day.”
Correct answer: A
Rationale: The correct instruction for the nurse to give the client who is starting on antihypertensive medication is to 'Get up and change positions slowly.' Antihypertensive medications can cause orthostatic hypotension, a drop in blood pressure when changing positions, so changing positions slowly helps prevent this adverse effect. Choice B about avoiding aged cheese and smoked meat is more relevant for clients taking monoamine oxidase inhibitors (MAOIs) due to potential interactions. Choice C regarding reporting unusual bruising or bleeding is more applicable for clients on anticoagulants. Choice D about consuming consistent amounts of vitamin K-containing foods daily is important for clients taking warfarin, not antihypertensive medications.
3. A client with diabetes mellitus type 2 is prescribed liraglutide. The nurse should include which instruction in the client's teaching plan?
- A. Administer this medication once a week.
- B. Administer this medication once a month.
- C. Administer this medication twice a day.
- D. Administer this medication once a day.
Correct answer: D
Rationale: The correct answer is to administer liraglutide once a day. Liraglutide is typically prescribed to be taken once daily, as directed by the healthcare provider. This dosing schedule helps maintain consistent levels of the medication in the body to effectively manage blood sugar levels in clients with diabetes mellitus type 2. Option A, administering once a week, is incorrect as it would not provide consistent control of blood sugar levels. Option B, administering once a month, is also incorrect as it is not the recommended dosing frequency for liraglutide. Option C, administering twice a day, is inaccurate as liraglutide is not typically dosed in this manner. It is important for the nurse to emphasize the importance of adherence to the prescribed dosing regimen to achieve optimal therapeutic outcomes.
4. While starting an intravenous infusion (IV) for a client, the nurse notices that her gloved hands get spotted with blood. The client has not been diagnosed with any infection transmitted via the bloodstream. Which of the following should the nurse do as soon as the task is completed?
- A. Remove the gloves carefully and follow with hand hygiene
- B. Change gloves and continue
- C. Wash hands immediately without removing gloves
- D. Report the incident to the supervisor
Correct answer: A
Rationale: After completing the task, the nurse should remove the gloves carefully and follow with hand hygiene. This practice is crucial to prevent the transmission of any potential pathogens, maintain cleanliness, and reduce the risk of infection. Changing gloves and continuing without proper hand hygiene may lead to contamination. Washing hands immediately without removing gloves is not recommended as it does not ensure thorough hand hygiene. Reporting the incident to the supervisor should be done if there are specific protocols in place for such incidents, but immediate hand hygiene is the priority in this scenario to ensure patient and nurse safety.
5. Which of the following illnesses causes degeneration of the central nervous system?
- A. Tay-Sachs disease
- B. Cystic fibrosis
- C. Turner syndrome
- D. Klinefelter syndrome
Correct answer: A
Rationale: Tay-Sachs disease is a genetic disorder that causes a progressive degeneration of the central nervous system, particularly in infants. Choice B, Cystic fibrosis, is a genetic disorder that primarily affects the lungs and digestive system, not the central nervous system. Choices C and D, Turner syndrome and Klinefelter syndrome, are chromosomal disorders that do not directly involve degeneration of the central nervous system.
