A nurse is providing preoperative teaching to a client about the administration of morphine via a PCA pump.
Which of the following statements by the client indicates an understanding of the teaching?
"Using this machine increases my risk of overdose."
"I can get pain medication any time as long as I press the button."
"My partner can press my pain medication button for me if I am sleeping."
"I will receive a limited amount of pain medication when I press the button." .
The Correct Answer is D
The correct answer is D.
Choice A reason: “A. Using this machine increases my risk of overdose.” This statement is incorrect because PCA pumps are designed with safety mechanisms to prevent overdose. The pump is programmed to deliver a specific dose of medication at set intervals, and it will not dispense more medication than what is prescribed by the healthcare provider.
Choice B reason: “B. I can get pain medication any time as long as I press the button.” While it is true that the patient can self-administer medication, PCA pumps have a lockout interval that prevents the machine from delivering another dose until a certain amount of time has passed, ensuring that the patient cannot receive medication too frequently.
Choice C reason: “C. My partner can press my pain medication button for me if I am sleeping.” This statement is incorrect. Only the patient should press the button on the PCA pump to ensure that the medication is administered safely and according to the patient’s current level of pain. Allowing someone else to press the button could lead to unsafe dosing.
Choice D reason: “D. I will receive a limited amount of pain medication when I press the button.” This is the correct statement. The PCA pump allows the patient to administer a controlled amount of pain medication within safe limits set by the healthcare provider. The pump is programmed to deliver a specific dose of medication, and there is a limit to the number of doses that can be administered per hour.

Correct Answer is D
Explanation
Choice A rationale:
Managing conflict within the group is an important skill, but it is more appropriate for the working phase of group therapy. During the orientation phase, the focus is on establishing trust, setting group norms, and creating a safe environment. Conflict resolution skills become more relevant as the group progresses.
Choice B rationale:
Encouraging the use of problem-solving skills is essential in group therapy, but it is a skill that is developed during the working phase. During the orientation phase, the nurse focuses on building rapport, creating a comfortable atmosphere, and explaining the purpose and goals of the group.
Choice C rationale:
Maintaining the group's focus on identified issues is a crucial aspect of the orientation phase. The nurse should guide the discussion to ensure that participants understand the purpose of the group and stay on topic. This helps in establishing clear goals and expectations for the group sessions.
Choice D rationale:
Establishing a rapport with group members is a primary goal of the orientation phase. Building trust and a therapeutic relationship with the adolescents creates a supportive environment where they feel comfortable sharing their experiences and emotions. A strong rapport enhances the effectiveness of the support group.
Correct Answer is B
Explanation
The correct answer is Choice b: New onset of hearing loss.
Gentamicin, a potent aminoglycoside antibiotic, is renowned for its propensity to cause ototoxicity, particularly manifesting as new-onset hearing loss. Ototoxicity refers to damage to the inner ear structures responsible for hearing and balance, primarily the cochlea and vestibular apparatus. The mechanism of gentamicin-induced ototoxicity involves its accumulation in the endolymphatic fluid of the inner ear, leading to direct toxicity to the sensory hair cells and subsequent hearing impairment.
Manifestations of gentamicin-induced ototoxicity can vary, ranging from subtle high-frequency hearing loss to profound sensorineural deafness. Patients may experience tinnitus (ringing in the ears), difficulty hearing in noisy environments, and imbalance or vertigo. Notably, gentamicin-induced hearing loss is often irreversible and may progress even after discontinuation of the medication.
Now, let's delve into the rationales for the other choices:
Choice a: Hypotension Gentamicin administration is not typically associated with hypotension. However, systemic side effects such as nephrotoxicity and neurotoxicity can occur, particularly with prolonged or high-dose therapy. Nephrotoxicity may manifest as acute kidney injury, characterized by a rise in serum creatinine and blood urea nitrogen levels, oliguria, and fluid-electrolyte imbalances. Neurotoxicity, on the other hand, can lead to symptoms like muscle weakness, paresthesia, and confusion. Monitoring of blood pressure is essential in patients receiving gentamicin, but hypotension is not a direct adverse effect of the medication.
Choice c: Hyperthermia Gentamicin therapy is aimed at treating bacterial infections, such as pyelonephritis, and does not typically induce hyperthermia. Pyelonephritis itself is associated with fever, chills, and flank pain due to the inflammatory response to the urinary tract infection. Administration of gentamicin aims to eradicate the causative bacteria and resolve the underlying infection, which should, in turn, alleviate fever. However, persistent or worsening fever despite antibiotic therapy may indicate treatment failure or the presence of complicating factors, warranting further evaluation and management.
Choice d: Slurred speech Slurred speech is not a recognized adverse effect of gentamicin. Instead, it may suggest central nervous system involvement, such as cerebrovascular accidents (strokes), intoxication, or neurological disorders affecting speech production. Gentamicin primarily exerts its toxic effects on the inner ear structures, leading to auditory dysfunction rather than impairments in speech articulation. Therefore, the presence of slurred speech would prompt an assessment for alternative etiologies unrelated to gentamicin therapy.
In conclusion, while gentamicin is an effective antibiotic for treating infections, it carries the risk of ototoxicity, particularly manifested as new-onset hearing loss. Careful monitoring for this adverse effect is crucial to promptly identify and manage potential complications.
