A 93-year-old female with a history of Alzheimer's Disease gets admitted to an Alzheimer's unit. The patient has exhibited signs of increased confusion and limited stability with gait. Moreover, the patient is refusing to use a w/c. Which of the following is the most appropriate course of action for the nurse?

Correct Answer: B

Rationale: For a 93-year-old female with Alzheimer's Disease exhibiting signs of increased confusion and limited stability with gait, recommending family members to bring pictures to the patient's room is the most appropriate course of action. Visual stimulation in the form of pictures may help decrease signs of confusion and provide comfort to the patient. Option A is incorrect as isolating the patient in her room at all times may worsen her condition by further limiting stimulation and interaction. Option C is incorrect as speech therapy may not directly address the current issues of confusion and gait instability. Option D is incorrect as pushing a wheelchair may not be safe for the patient if she is refusing to use it, potentially leading to falls or further distress.

Correct Answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

Correct Answer: A

Rationale: When a client suffers an ankle sprain, the nurse should teach them to use cold applications to the sprain during the first 24-48 hours. Cold applications are believed to produce vasoconstriction and reduce the development of edema. Expecting disability to decrease within the first 24 hours of injury (choice B) is incorrect as disability and pain are anticipated to increase during the first 2-3 hours after injury. Expecting pain to decrease within 3 hours after injury (choice C) is also incorrect as pain and swelling usually increase initially. Beginning progressive passive and active range of motion exercises immediately (choice D) is not recommended; these exercises are usually started 2-5 days after the injury, according to the physician's recommendation. Treatment for a sprain involves support, rest, and alternating cold and heat applications. X-ray pictures are often necessary to rule out any fractures.

Correct Answer: C

Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.

Correct Answer: D

Rationale: When dealing with a patient with active TB and HIV, the nurse should wear goggles, a mask, gloves, and a gown to protect themselves from potential exposure to infectious agents through respiratory secretions or blood. Surgical cap and proper shoewear are not specifically required for this procedure, making option B incorrect. Double gloving is not necessary in this scenario, hence option C is incorrect. Therefore, the correct choice is D as it includes all the essential protective equipment for this situation.
