The normal respiration rate for adults is

Correct Answer: C

Rationale: The correct answer is C: 2-20 breaths per minute. This range is the most accurate representation of the normal respiration rate for adults, which typically falls between 12-18 breaths per minute. Options A, B, and D are incorrect because A (8-30 breaths per minute) and B (5-25 breaths per minute) have wider ranges that may include abnormal rates, while D (8-0 breaths per minute) is illogical since a respiration rate of 0 would indicate no breathing, which is incompatible with life. Therefore, option C is the most precise and accurate range for the normal respiration rate in adults.

Correct Answer: D

Rationale: The correct answer is D: Irritability. Constipation can lead to discomfort and irritability due to the buildup of stool in the intestines. Liquid or frequent stools (A) are typically associated with diarrhea, not constipation. Rapid heart rate (B) is not a common sign of constipation. Fecal incontinence (C) refers to the inability to control bowel movements, which is the opposite of constipation. Therefore, irritability (D) is the most relevant sign of constipation.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Bladder retraining involves gradually increasing time between bathroom trips. 2. Encouraging plenty of fluids helps improve bladder capacity and control. 3. Fluid restriction can worsen incontinence. 4. Monitoring fluid intake is crucial in bladder retraining. 5. Keeping a record of bladder habits helps track progress. Summary: B: Keeping a record of bladder habits is essential. C: Wearing gloves when handling body wastes is important for infection control. D: Providing gentle reminders about urination time is helpful in bladder retraining.

Correct Answer: A

Rationale: The correct answer is A: It strengthens their effects. Moisture enhances the transfer of heat/cold to the body, intensifying the effects of warm/cold applications. This accelerates the desired therapeutic outcome. Choices B, C, and D are incorrect. B is inaccurate because moisture does not reduce the effects but rather enhances them. C is irrelevant as moisture does not affect the likelihood of causing injury. D is incorrect as the duration of application is not solely determined by moisture.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Oxygen supports combustion, increasing fire risk. 2. Open flames near oxygen can lead to fires. 3. Nursing assistants must ensure safety by preventing open flames. 4. Oxygen levels should be adjusted by licensed healthcare professionals, not nursing assistants. 5. Clogged tubing requires replacement, not just cleaning. 6. Skin problems require evaluation and intervention by healthcare providers, not nursing assistants. Summary: Choice A is correct as it addresses the critical safety concern of fire hazard with oxygen equipment. Choices B, C, and D are incorrect as they involve tasks that are beyond the scope of practice for nursing assistants.
