When are standard walkers typically used?

Correct Answer: C

Rationale: Standard walkers are typically used for clients who have poor balance, cardiac problems, or those who cannot use crutches or a cane. The rationale is correct in stating that a walker is suitable for individuals needing to bear partial weight and having strength in their wrists and arms to propel the walker forward. Choices A, B, and D are incorrect because they do not accurately reflect the main reasons why standard walkers are used in clinical practice. Using a walker is not solely about having weak arms, good hand strength, a broken leg, experienced amputation, or an autoimmune disease. The primary focus is on addressing balance issues, cardiac problems, or the inability to use crutches or a cane effectively.

Correct Answer: A

Rationale: When an elderly client with cancer is receiving NSAID therapy, monitoring BUN (blood urea nitrogen) and creatinine levels is crucial. NSAIDs can cause renal toxicity, especially in the elderly. BUN and creatinine levels help assess renal function and detect early signs of renal impairment. Monitoring creatinine alone (Choice B) is not sufficient as BUN provides complementary information about renal function. Monitoring hemoglobin (Hgb) and hematocrit (Hct) (Choice C) is important for assessing anemia but not specific to NSAID therapy in the elderly. CFT (Choice D) is not a standard abbreviation in this context, and monitoring coagulation function is not directly related to NSAID therapy in this scenario.

Correct Answer: C

Rationale: The correct answer is 6 liters/minute. When a client needs oxygen therapy, the highest flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Higher flow rates must be delivered by a mask. Choices A, B, and D are incorrect because they suggest flow rates that exceed what can be effectively delivered through a nasal cannula.

Correct Answer: C

Rationale: To provide total oral care to a client, the nurse should first assemble all necessary equipment. Placing the client in a side-lying position helps fluids to easily flow out or pool in the side of the mouth for suctioning, thus preventing aspiration. Additionally, placing a towel under the client's chin and a curved basin against the chin helps to maintain cleanliness during the procedure. Choice A is incorrect because the client should be placed in a side-lying position, not a semi-Fowler's position which is used for respiratory issues. Choice B is incorrect as it does not emphasize the importance of proper positioning for effective oral care. Choice D is incorrect as it oversimplifies the procedure by focusing only on cleaning the mouth without considering the importance of positioning and preparation.

Correct Answer: B

Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.
