Residents who have difficulty ______ may require thickened liquids.

Correct Answer: B

Rationale: The correct answer is B: Swallowing. Difficulty swallowing, also known as dysphagia, can lead to aspiration of thin liquids, which can cause respiratory issues. Thickened liquids help prevent aspiration and are often recommended for individuals with swallowing difficulties. Residents with difficulty walking (choice A), digesting food (choice C), or gaining weight (choice D) may have different dietary or medical needs, but the primary concern in this context is swallowing safety.

Correct Answer: A

Rationale: Rationale for Correct Answer A: Bladder retraining involves encouraging regular bathroom visits and adequate fluid intake to improve bladder control. By encouraging the resident to drink plenty of fluids, even if incontinence is a problem, the bladder can be trained to hold urine for longer periods, reducing the frequency of accidents. Summary of Incorrect Choices: B: Keeping a record of the resident's bladder habits is essential in bladder retraining to track progress and identify patterns. Not keeping a record would hinder the effectiveness of the retraining process. C: Wearing gloves when handling body wastes is crucial for infection control and preventing the spread of pathogens. Not wearing gloves poses health risks to both the NA and the resident. D: It is not the NA's role to dictate the resident's urination time. The focus should be on encouraging proper bladder habits, not pressuring the resident, which can lead to anxiety and worsen the issue.

Correct Answer: A

Rationale: The correct answer is A: Moisture strengthens the effects of warm and cold applications by facilitating heat transfer. When moisture is present, it enhances the conduction of heat/cold to the body, intensifying the therapeutic effects. This increased heat/cold transfer helps in achieving the desired outcomes more efficiently. Explanation of Incorrect Choices: B: Moisture does not reduce the effects of warm and cold applications; it actually enhances them. C: Moisture does not directly affect the likelihood of causing injury; proper application technique is key to prevent injury. D: Moisture does not necessarily allow applications to be applied for a longer time; the duration of application should be based on individual needs and treatment goals.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Oxygen supports combustion, making it a fire hazard. 2. Nursing assistants should prevent open flames near oxygen to avoid fire accidents. 3. This guideline ensures safety for both patients and staff. 4. Answer A is directly related to oxygen equipment safety. Summary of why other choices are incorrect: B: Nursing assistants do not adjust oxygen levels; this is the responsibility of licensed medical professionals. C: Replacing clogged tubing is important, but not specific to working around oxygen equipment. D: Nursing assistants do not prescribe medical devices; this is the responsibility of healthcare providers.

Correct Answer: B

Rationale: The correct answer is B: Some memory loss occurs. As people age, it is common to experience mild memory decline due to changes in brain structure and function. This is a normal part of the aging process and does not necessarily indicate a serious cognitive issue. Choices A, C, and D are incorrect because aging typically does not lead to speeding up of responses and reflexes, increased sensitivity of nerve endings in the skin, or improvement in senses such as vision and taste. These changes are more likely to occur due to external factors or individual differences rather than normal age-related changes in the nervous system.
