\What should the nurse teach an older client with TIA?

Correct Answer: C

Rationale: The correct answer is C: To comply with the medication regimen. Teaching the older client with TIA to comply with medication regimen is crucial in preventing further TIAs or strokes. Medications like antiplatelets or anticoagulants are often prescribed to manage TIA. This education empowers the client to actively participate in their own health management. Incorrect choices: A: Not to worry about the symptoms that are part of the normal aging process - This is incorrect as TIA symptoms are not considered a normal part of aging and should not be ignored. B: To admit oneself to a rehabilitation center or a nursing home for rehabilitation - This is incorrect as it is not the primary intervention for managing TIA. D: To observe any changes in the nails and skin - This is incorrect as it is not directly related to managing TIA.

Correct Answer: C

Rationale: The correct answer is C: 2, 3, and 4. High cholesterol, cigarette smoking, and a sedentary lifestyle are modifiable risk factors for developing hypertension. High cholesterol can lead to atherosclerosis, increasing blood pressure. Smoking can constrict blood vessels, raising blood pressure. Sedentary lifestyle can lead to obesity and overall poor cardiovascular health, contributing to hypertension. Race and age are non-modifiable risk factors. Choice A is incorrect because it includes race, a non-modifiable factor. Choice B is incorrect because it includes age, which is also non-modifiable. Choice D is incorrect because it includes all factors, including non-modifiable ones.

Correct Answer: A

Rationale: Correct Answer: A: Cover wound with moist sterile dressing Rationale: 1. Covering the wound with a moist sterile dressing helps maintain a clean and moist environment, promoting wound healing. 2. Moist dressing prevents the wound from drying out and minimizes the risk of infection. 3. The moist environment supports healing by promoting cell growth and preventing tissue damage. 4. It protects the exposed bowel from further injury and contamination. Summary: B: Finding out how this happened is important but not an immediate priority for patient care. C: Placing sterile dry gauze can lead to the wound drying out and hinder healing. D: Pouring sterile water into the wound is not recommended as it can introduce contaminants and is not considered standard care for this situation.

Correct Answer: C

Rationale: The correct answer is C: 5% dextrose in 0.9% NaCl. This solution is hypertonic because it has a higher osmolarity compared to the other choices. The presence of dextrose and NaCl in this solution increases its solute concentration, causing water to move out of the cells by osmosis. Normal saline (A) and 0.45% NaCl (B) are isotonic solutions, meaning they have the same osmolarity as body fluids. 0.225% NaCl (D) is a hypotonic solution with lower osmolarity than body fluids.

Correct Answer: D

Rationale: The correct action for the nurse to take first is to obtain a Doppler and recheck the pedal pulses. This is the correct choice because it allows the nurse to further assess the circulation in the lower extremities. By using a Doppler, the nurse can accurately detect the presence or absence of pedal pulses, which is crucial in evaluating the severity of the patient's condition. This step provides objective data that can guide the next course of action. Choice A is incorrect because emergency surgery should not be anticipated without further assessment. Choice B is incorrect as assessing apical and radial pulses is not relevant in this situation. Choice C is incorrect as elevating the foot of the bed and applying warm compress may not address the underlying circulation issue.

Correct Answer: A

Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action. Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.

Correct Answer: B

Rationale: The correct answer is B: Efferent. Efferent neurons transmit signals from the central nervous system to muscles and glands, controlling movement and secretion. Afferent neurons carry signals from sensory receptors to the central nervous system, not towards muscles or glands. "Affective" relates to emotions, not neural function. "Effective" does not describe the direction of signal transmission in the nervous system. Therefore, B is the correct choice.

Correct Answer: B

Rationale: The correct answer is B. This statement shows an understanding of reducing HIV transmission by promoting harm reduction strategies like needle exchange programs, which help prevent sharing of contaminated needles. This approach is evidence-based and effective in reducing the spread of HIV among injection drug users. Choice A is incorrect because breastfeeding by HIV-positive mothers can transmit the virus to infants. Choice C is incorrect as birth control pills do not protect against HIV, only against pregnancy. Choice D is incorrect as natural skin condoms do not provide the same level of protection against HIV as latex condoms do.

Correct Answer: B

Rationale: Step 1: High cholesterol levels contribute to the buildup of plaque in arteries, leading to atherosclerosis and increasing the risk of coronary artery disease. Step 2: Atherosclerosis can result in a blockage of blood flow to the heart, causing a myocardial infarction (MI). Step 3: Age is a risk factor for CAD but not directly linked to MI development. Step 4: Medication usage may impact risk factors but is not a direct cause of MI. Step 5: Gender can influence risk but is not the primary factor in MI development.
