About 55% of blood is made up of _______.

Correct Answer: C

Rationale: The correct answer is C: Plasma. Plasma makes up about 55% of blood volume and consists of water, proteins, electrolytes, hormones, and waste products. It carries nutrients, gases, and waste products throughout the body. Erythrocytes (A) are red blood cells and make up about 45% of blood volume. Leukocytes (B) are white blood cells, which only constitute a small percentage of blood volume. Platelets (D) are cell fragments involved in blood clotting and make up a very small portion of blood volume. Plasma is the correct answer because it is the main component of blood by volume and serves various essential functions.

Correct Answer: C

Rationale: The correct answer is C: Medication or surgery. Seizures are typically managed with medication to control or prevent them. Surgery may be considered in cases where medication is ineffective. Range of motion exercises (A) and physical therapy (D) are not standard treatments for seizures. Restraining the resident (B) is not an appropriate or effective method for managing seizures.

Correct Answer: A

Rationale: The correct answer is A: The person is obese. Obesity is a significant risk factor for developing type 2 diabetes as excess body fat can lead to insulin resistance. This impairs the body's ability to regulate blood sugar levels effectively, increasing the likelihood of developing diabetes. Summary of why the other choices are incorrect: B: Malnourishment does not directly increase the likelihood of diabetes. It may lead to other health issues but is not a primary risk factor for diabetes. C: Incontinence is a condition related to bladder control and does not have a direct correlation with diabetes risk. D: Chronic obstructive pulmonary disorder (COPD) is a lung disease and is not directly linked to an increased risk of diabetes.

Correct Answer: B

Rationale: The correct answer is B because when a resident has one weaker leg, the cane should be held on the stronger side to provide support and stability. This helps to shift weight away from the weaker leg, reducing the risk of falls. Holding the cane on the weaker side (choice A) would not provide adequate support. Using a wheelchair (choice C) is not necessary for someone with one weaker leg. Keeping the resident in bed (choice D) is not ideal as it limits mobility and can lead to muscle weakness.

Correct Answer: D

Rationale: Postmortem care involves caring for the body after death, including cleaning, preparing for viewing, and ensuring dignity. Pathologist examination (A) focuses on determining cause of death but isn't part of postmortem care. Meeting emotional needs (B) and grief counseling (C) are important but not specific to postmortem care. Therefore, choice D is correct as it directly pertains to caring for the body after death.
