HESI RN Nursing Leadership and Management Exam 5
1. When caring for a female client with a history of hypoglycemia, Nurse Ruby should avoid administering a drug that may potentiate hypoglycemia. Which drug fits this description?
- A. Sulfisoxazole (Gantrisin)
- B. Mexiletine (Mexitil)
- C. Prednisone (Orasone)
- D. Lithium carbonate (Lithobid)
Correct answer: A
Rationale: The correct answer is A, Sulfisoxazole (Gantrisin). Sulfisoxazole is known to potentiate hypoglycemia, making it unsafe for clients with a history of hypoglycemia. Choice B, Mexiletine, is a medication used to treat certain heart rhythm problems and is not associated with hypoglycemia. Choice C, Prednisone, is a corticosteroid and does not potentiate hypoglycemia. Choice D, Lithium carbonate, is commonly used to treat bipolar disorder and does not typically potentiate hypoglycemia. Therefore, the drug that Nurse Ruby should avoid in this case is Sulfisoxazole (Gantrisin) to prevent worsening the client's hypoglycemic condition.
2. The nurse is assessing an older adult client and determines that the client's left upper eyelid droops, covering more of the iris than the right eyelid. Which description should the nurse use to document this finding?
- A. Ptosis on the left eyelid.
- B. Nystagmus.
- C. Astigmatism.
- D. Exophthalmos.
Correct answer: A
Rationale: The correct answer is A: 'Ptosis on the left eyelid.' Ptosis is the term used to describe an eyelid droop that covers a large portion of the iris, which may be caused by issues with the oculomotor nerve or eyelid muscles. Choice B, 'Nystagmus,' refers to involuntary eye movements and is not related to eyelid drooping. Choice C, 'Astigmatism,' is a refractive error affecting vision due to an irregularly shaped cornea or lens, not an eyelid condition. Choice D, 'Exophthalmos,' is a protrusion of the eyeball associated with conditions like hyperthyroidism, not eyelid drooping.
3. A client who is receiving digoxin (Lanoxin) daily has a serum potassium level of 3.0 mEq/L and is complaining of anorexia. A healthcare provider prescribes a digoxin level to rule out digoxin toxicity. A nurse checks the results, knowing that which of the following is the therapeutic serum level (range) for digoxin?
- A. 3 to 5 ng/mL
- B. 0.5 to 2 ng/mL
- C. 1.2 to 2.8 ng/mL
- D. 3.5 to 5.5 ng/mL
Correct answer: B
Rationale: The therapeutic serum level for digoxin ranges from 0.5 to 2 ng/mL. This range is considered optimal for therapeutic effects while minimizing the risk of toxicity. Levels above 2 ng/mL may lead to digoxin toxicity, which can manifest as anorexia among other symptoms. Therefore, the nurse should be vigilant in monitoring the digoxin levels to ensure the client's safety and therapeutic effectiveness of the medication.
4. The healthcare provider is applying a topical corticosteroid to a client with eczema. The healthcare provider should monitor for the potential of increased systemic absorption of the medication if the medication were being applied to which of the following body areas?
- A. Back
- B. Axilla
- C. Soles of the feet
- D. Palms of the hands
Correct answer: B
Rationale: The axilla has thinner skin, making it more permeable to topical medications. Areas with thinner skin, like the axilla, allow for higher systemic absorption of topical corticosteroids.
5. Which of the following molecules contains the code required for replication?
- A. Deoxyribonucleic acid (DNA)
- B. Transfer RNA (tRNA)
- C. Messenger RNA (mRNA)
- D. Ribonucleic acid (RNA)
Correct answer: A
Rationale: The correct answer is A: Deoxyribonucleic acid (DNA). DNA contains the genetic information essential for replication, ensuring the accurate transmission of genetic material from one generation to the next. Choice B, Transfer RNA (tRNA), is involved in protein synthesis, not replication. Choice C, Messenger RNA (mRNA), carries genetic information from DNA to the ribosome but does not contain the code for replication. Choice D, Ribonucleic acid (RNA), is a broader category that includes both mRNA and tRNA, but the specific molecule containing the code required for replication is DNA.
