Correct Answer: B

Rationale: The correct answer is B: Implement an automatic sign-off. This guideline helps reduce data entry errors by ensuring that all entries are completed and saved before exiting the system, thus maintaining confidentiality. Bypassing the firewall (A) would compromise data security. Creating a password with just letters (C) may not be secure enough. Using a programmed speed-dial key when faxing (D) is unrelated to reducing data entry errors or maintaining confidentiality.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Hearing-impaired patient is likely unable to hear during an MRI due to loud noises. 2. Nurse needs to use alternative communication methods like writing or gestures. 3. Sign language interpreter may not be necessary for an MRI. 4. Lip reading may be challenging due to the noisy MRI environment. 5. Interaction should be adapted to accommodate the patient's communication needs.

Correct Answer: C

Rationale: Rationale: Ganciclovir is the correct answer for the acute stage of CMV retinitis in AIDS patients. It is an antiviral drug that specifically targets CMV. Ganciclovir works by inhibiting viral DNA synthesis, effectively controlling CMV replication in the eye. Pilocarpine (A) is a miotic used for glaucoma, not for CMV retinitis. Penicillin (B) is an antibiotic effective against bacterial infections, not viral infections like CMV. Gentamicin (D) is an antibiotic used to treat bacterial infections, not viral infections like CMV.

Correct Answer: B

Rationale: The correct answer is B: Hearing loss may occur with a decibel level in this range. Prolonged exposure to sound levels between 80-90 dB can lead to hearing damage over time. This range is considered high and can cause irreversible damage to the hair cells in the inner ear, leading to hearing loss. Choices A, C, and D are incorrect because hearing can be affected at this decibel level, the sound can be harsh to the ear, and earplugs can help reduce the risk of hearing damage at these levels.

Correct Answer: D

Rationale: The correct answer is D, combining multiple objective measures with subjective measures. This approach provides a comprehensive assessment of the patient's nutritional status by incorporating both quantitative data (objective measures) such as weight, BMI, and laboratory values, as well as qualitative information (subjective measures) like dietary history and appetite changes. By combining these measures, the nurse can obtain a more holistic view of the patient's nutritional status, allowing for better identification of nutritional deficiencies or excesses. This method enhances the accuracy and reliability of the assessment compared to relying solely on one type of measure. Choice A is incorrect because nutritional assessment is crucial even in the presence of chronic disease to address potential malnutrition risks. Choice B is incorrect as the Mini Nutritional Assessment is not intended for pediatric patients but for adults. Choice C is incorrect as using a single tool may not capture the full complexity of the patient's nutritional status.
