A nurse is teaching a client about family planning using the basal body temperature method.
Which of the following instructions should the nurse include in the teaching?

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.

Choice A rationale:

Making decisions about health care on clients' behalf without their involvement violates the principle of patient autonomy. Patients have the right to be actively involved in decisions about their own care and treatment plans. Encouraging shared decision-making and respecting patients' choices are essential aspects of nursing advocacy.

Choice B rationale:

Promoting health care access is a fundamental aspect of advocacy in client care. Nurses should advocate for their patients' access to necessary healthcare services, treatments, and resources. This includes ensuring that patients have access to appropriate medical facilities, specialists, medications, and therapies. Advocating for health care access helps patients receive timely and appropriate care, improving their overall health outcomes.

Choice C rationale:

Encouraging clients to seek further information from the provider is crucial for informed decision-making. Providing patients with accurate and relevant information enables them to make educated choices about their health. Nurses can facilitate this process by clarifying medical information, explaining treatment options, and addressing patients' concerns. Informed patients are better equipped to actively participate in their care and advocate for their own needs.

Choice D rationale:

Addressing client needs when providing resources is an essential aspect of nursing advocacy. Nurses should assess their patients' individual needs and collaborate with other healthcare professionals to provide appropriate resources and support. This can include coordinating social services, arranging for home healthcare, or connecting patients with support groups. Meeting clients' needs ensures that they receive comprehensive care, promoting their overall well-being.

Choice E rationale:

Honoring family requests to withhold medical information can be ethically challenging. While family members play a significant role in a patient's life, confidentiality and patient autonomy must be respected. In most cases, healthcare providers should prioritize communicating directly with the patient, respecting their right to make decisions about their own health information. Exceptions may arise in situations involving legal guardianship or when patients are unable to communicate their preferences. However, the default approach should be to involve the patient directly in decisions about their healthcare information.
