HESI RN
Biology Test
1. What do prokaryotic cells lack in comparison to eukaryotic cells?
- A. A defined nucleus and a series of membrane-bound organelles
- B. A defined nucleus and no membrane-bound organelles
- C. No defined nucleus and a series of membrane-bound organelles
- D. No defined nucleus and no membrane-bound organelles
Correct answer: D
Rationale: Prokaryotic cells are characterized by the absence of a defined nucleus and membrane-bound organelles. Choice A is incorrect because prokaryotic cells lack membrane-bound organelles. Choice B is incorrect because prokaryotic cells lack both a defined nucleus and membrane-bound organelles. Choice C is incorrect as prokaryotic cells have no defined nucleus. Therefore, the correct answer is D.
2. Sildenafil (Viagra) is prescribed to treat a client with erectile dysfunction. A nurse reviews the client's medical record and would question the prescription if which of the following is noted in the client's history?
- A. Neuralgia
- B. Insomnia
- C. Use of nitroglycerin
- D. Use of multivitamins
Correct answer: C
Rationale: The correct answer is C. Sildenafil (Viagra) enhances the vasodilating effect of nitric oxide and is contraindicated with the concurrent use of organic nitrates and nitroglycerin. Using nitroglycerin together with Viagra can lead to severe hypotension and cardiovascular collapse, making it unsafe to combine both medications.
3. In Reproductive Health services, decision-making about RH matters is mostly done by:
- A. The Woman's parents
- B. The Man's parents
- C. The Husband
- D. The Wife
Correct answer: C
Rationale: In many societies, the husband often plays a significant role in decision-making about reproductive health matters, making choice C the correct answer. While the woman's parents might have some influence in certain cultures, the husband typically has a more direct role in such decisions. Choices A and B are less likely as the focus is on the immediate family unit rather than extended family members. Choice D, the wife, is less common in patriarchal societies where men usually have more authority in decision-making regarding reproductive health matters.
4. What action should the nurse take after applying gloves to irrigate a client's indwelling urinary catheter using an open technique?
- A. Empty the client's urinary drainage bag.
- B. Draw up the irrigating solution into the syringe.
- C. Secure the client's catheter to the drainage tubing.
- D. Use aseptic technique to instill the irrigating solution.
Correct answer: B
Rationale: After applying gloves to irrigate an indwelling urinary catheter using an open technique, the next step for the nurse is to draw up the irrigating solution into the syringe. This step is crucial as it ensures that the solution is ready to be instilled through the catheter to maintain its patency and prevent blockages. Option A is incorrect as emptying the client's urinary drainage bag is not the immediate next step in the irrigation process. Option C is incorrect as securing the client's catheter to the drainage tubing is not necessary at this stage. Option D is incorrect as the question pertains to the action immediately after applying gloves and does not involve instilling the irrigating solution yet.
5. A client is admitted for bipolar disorder and alcohol withdrawal, depressive phase. Based on which assessment finding will the RN withhold the clonidine (Catapres) prescription?
- A. Blood pressure readings of 90/62 mmHg to 92/58 mmHg.
- B. Pulse rate of 68-78 BPM.
- C. Temperature of 99.5-99.7°F.
- D. Respiration rate of 24 breaths per minute.
Correct answer: A
Rationale: In this scenario, the correct answer is A. Clonidine, such as Catapres, is a medication that can lower blood pressure. Therefore, if a client has low blood pressure readings, like 90/62 mmHg to 92/58 mmHg, the registered nurse should withhold the clonidine prescription to prevent further lowering of blood pressure which could lead to adverse effects. Choices B, C, and D are incorrect because they are within normal ranges and do not present a contraindication for the administration of clonidine in this context.
