Nursing Process Practice Questions Quizlet

Correct Answer: C

Rationale: The correct answer is C: "Divided doses produce greater cytotoxic effects on the diseased cells." Dividing the doses of the antimetabolite allows for more consistent levels of the drug in the bloodstream, ensuring sustained exposure to the cancer cells. This continuous exposure enhances the drug's cytotoxic effects, increasing its efficacy in targeting and destroying the diseased cells. Options A and B provide vague or incorrect information, while option D is misleading as antimetabolites do not prevent cell division, but rather disrupt DNA synthesis.

Correct Answer: D

Rationale: The correct answer is D: Stapedectomy. This procedure is used to correct otosclerosis by removing the stapes bone and replacing it with a prosthetic device. This restores normal hearing by allowing sound waves to travel through the ear properly. Myringotomy (A) is a procedure to drain fluid from the middle ear, not to correct otosclerosis. Mastoidectomy (B) is the removal of infected mastoid air cells, not related to otosclerosis. Myringoplasty (C) is a surgical procedure to repair a perforated eardrum, not used for otosclerosis. Stapedectomy is the most appropriate choice for correcting otosclerosis as it directly addresses the abnormal bone growth in the middle ear.

Correct Answer: C

Rationale: The correct answer is C: �You may not be able to use desmopressin nasally if you have nasal discharge or blockage.� Rationale: 1. Desmopressin is available in intranasal form for diabetes insipidus. 2. Nasal discharge or blockage may prevent proper absorption of the medication. 3. Instructing the client about this potential issue ensures optimal drug effectiveness. Summary: A: Incorrect. Temperature of desmopressin suspension doesn't affect its efficacy. B: Incorrect. A medical identification bracelet is necessary for chronic conditions like diabetes insipidus. D: Incorrect. Monitoring fluid intake and output is crucial when taking desmopressin.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Applying antibiotic ointment and placing the mother in reverse isolation are not appropriate for managing vesicles suspected to be herpes simplex virus (HSV) during labor. 2. HSV can be transmitted to the baby during vaginal delivery, leading to serious consequences. 3. Standard precautions should always be maintained to prevent the spread of infections. 4. Preparing for the possibility of a cesarean section and notifying the obstetrician about the vesicles are important steps to protect the baby and staff from potential harm.

Correct Answer: C

Rationale: The correct formula to calculate the appropriate morphine dose for the client is 5 mg/kg of body weight. This is the most suitable formula because morphine dosing is typically based on weight to ensure appropriate pain management and to prevent adverse effects. By using this formula, the nurse can calculate the exact dose based on the client's weight, providing personalized care. Choice A (1 mg/kg of body weight) is too low of a dose and may not effectively manage severe pain. Choice B (5 mg/70kg of body weight) is not ideal as it does not account for variations in weight among individuals. Choice D (10mg/70kg of body weight) would result in an overdose for most patients, potentially causing serious harm. Therefore, by using the formula of 5 mg/kg of body weight, the nurse can ensure that the morphine dose is appropriate and safe for the client.
