HESI Medical Surgical Practice Quiz
1. The patient is taking low-dose erythromycin prophylactically and will start cefaclor for treating an acute infection. The nurse should discuss this with the provider because taking both medications simultaneously can cause which effect?
- A. Decreased effectiveness of cefaclor.
- B. Increased effectiveness of cefaclor.
- C. Decreased effectiveness of erythromycin.
- D. Increased effectiveness of erythromycin.
Correct answer: A
Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.
2. Which of the following provides support and shape to the cell?
- A. Microtubules
- B. Microfilaments
- C. Cilia
- D. Microvilli
Correct answer: A
Rationale: Microtubules are fundamental components of the cytoskeleton in a cell, playing a crucial role in providing structural support and maintaining the cell's shape. They are composed of tubulin protein subunits and are involved in various cellular processes like cell division, intracellular transport, and cell motility. Microfilaments, on the other hand, are involved in cell movement and maintaining cell shape but are not primarily responsible for supporting the cell's overall structure. Cilia and microvilli are cellular projections that aid in movement and absorption, respectively, but they do not play a significant role in providing structural support to the cell.
3. The client is being instructed on the proper use of a metered-dose inhaler. Which instruction should be provided to ensure the optimal benefits from the drug?
- A. Fill your lungs with air through your mouth and then compress the inhaler.
- B. Compress the inhaler while slowly breathing in through your mouth.
- C. Compress the inhaler while inhaling quickly through your nose.
- D. Exhale completely after compressing the inhaler and then inhale.
Correct answer: B
Rationale: The correct technique for using a metered-dose inhaler involves compressing the inhaler while slowly breathing in through the mouth. This method helps ensure that the medication reaches deep into the lungs, allowing for optimal bronchodilation effect. Inhaling quickly through the nose or filling the lungs with air before compressing the inhaler are not recommended techniques for using a metered-dose inhaler effectively.
4. An adult female client with chronic kidney disease (CKD) asks the nurse if she can continue taking her over-the-counter medications. Which medication poses the greatest threat to this client?
- A. Magnesium hydroxide (Maalox).
- B. Birth control pills.
- C. Cough syrup containing codeine.
- D. Cold medication containing alcohol.
Correct answer: A
Rationale: The correct answer is A, Magnesium hydroxide (Maalox). In clients with chronic kidney disease (CKD), magnesium can accumulate to toxic levels as the kidneys are unable to excrete it efficiently. This can lead to hypermagnesemia, causing serious and potentially life-threatening complications. Birth control pills (choice B) are metabolized mainly by the liver and do not pose a significant threat to clients with CKD. Cough syrup containing codeine (choice C) should be used cautiously in CKD due to the risk of respiratory depression but does not pose as great a threat as magnesium accumulation. Cold medication containing alcohol (choice D) should be avoided in CKD but does not present the same level of danger as magnesium toxicity.
5. After informing an older client that an IV line needs to be inserted, the client becomes very apprehensive, loudly expressing a dislike for all healthcare providers and nurses. How should the nurse respond?
- A. Ask the client to remain quiet so the procedure can be performed safely.
- B. Concentrate on completing the insertion as efficiently as possible.
- C. Calmly reassure the client that the discomfort will be temporary.
- D. Tell the client a joke as a means of distraction from the procedure.
Correct answer: C
Rationale: In this situation, the nurse should respond by calmly reassuring the client that the discomfort from the IV insertion will be temporary. By providing reassurance and addressing the client's concerns, the nurse can help reduce the client's apprehension and create a more supportive environment for the procedure.
