Guidelines for the nursing assistant to give proper catheter care include

Correct Answer: C

Rationale: The correct answer is C because keeping the genital area clean is essential in preventing infection during catheter care. This step helps reduce the risk of introducing bacteria into the urinary tract, which can lead to urinary tract infections. Maintaining proper hygiene in the genital area also promotes overall comfort and well-being for the resident. A is incorrect as the drainage bag should be positioned below the level of the bladder to facilitate proper drainage. B is incorrect as disconnecting the catheter can introduce contaminants and increase the risk of infection. D is incorrect as hanging the drainage bag from the bedrail can cause backflow of urine and increase the risk of infection.

Correct Answer: A

Rationale: The correct answer is A: Lung strength decreases. As people age, their lung capacity decreases due to changes in lung tissue elasticity and muscle strength, leading to decreased respiratory function. This results in reduced lung strength and efficiency. Option B is incorrect as airways actually become less elastic with age, contributing to decreased lung function. Option C is incorrect as aging can lead to a weaker cough reflex. Option D is incorrect as oxygen levels in the blood do not typically increase with age; in fact, they may decrease due to reduced lung function.

Correct Answer: C

Rationale: The correct answer is C: Neuron. Neurons are the basic working units of the nervous system because they are specialized cells that transmit information through electrical and chemical signals. Neurons have a cell body, dendrites, and an axon, allowing them to receive, process, and send signals. The brain and spinal cord are made up of neurons but are not the basic working unit. Receptors are sensory organs that detect stimuli but do not transmit signals like neurons do. Therefore, the correct choice is C because neurons are essential for communication within the nervous system.

Correct Answer: B

Rationale: Validation therapy is the correct answer. It involves validating the feelings and beliefs of individuals with Alzheimer's disease (AD), even if they are not based in reality. This approach helps to reduce stress and anxiety by acknowledging and respecting their emotions. A: Reality orientation focuses on helping individuals with AD understand current time, place, and person, which is opposite to the approach mentioned in the question. C: Reminiscence therapy involves recalling past memories but does not necessarily involve validating false beliefs about living in the past. D: Remotivation therapy aims to increase motivation and engagement, but it is not specifically related to addressing the belief of living in the past.

Correct Answer: C

Rationale: The correct answer is C: Malignant. A malignant tumor is cancerous because it can invade nearby tissues and spread to other parts of the body. This term is used to describe tumors that are harmful and have the potential to be life-threatening. Incorrect choices: A: Opportunistic - This term is not related to tumor classification. Opportunistic refers to infections that occur when the immune system is weakened. B: Benign - Benign tumors are non-cancerous and do not invade nearby tissues or spread to other parts of the body. D: Ballistic - This term is unrelated to tumor classification and refers to the science of projectiles and firearms.
