1. For a patient who is blood type AB, which blood product can they receive?

A. Plasma from a type B donor
B. Whole blood from a type A donor
C. Packed RBCs from a type O donor
D. All of the above

Correct answer: C

Rationale: A patient with blood type AB has AB antigens on their red blood cells. This means they can only receive blood products that are compatible with these antigens. Choice A is incorrect because an AB patient cannot receive plasma from a type B donor due to the antibodies present in type B plasma. Choice B is incorrect because an AB patient cannot receive whole blood from a type A donor as it contains incompatible antigens. Choice C is the correct answer because an AB patient can receive packed RBCs from a type O donor. Type O donors have no A or B antigens, making their blood compatible for transfusion to recipients with any blood type. Therefore, choices A and B are incorrect, and the correct choice is C.

2. Which of the following is the most likely cause of constipation in a client?

A. Postponing bowel movement when the urge to defecate occurs
B. Intestinal infection
C. Antibiotic use
D. Food allergies

Correct answer: A

Rationale: The correct answer is to postpone bowel movement when the urge to defecate occurs. Clients who delay bowel movements by ignoring the urge to defecate or not evacuating promptly, such as in situations where they are not near a bathroom, are at higher risk of developing constipation. This behavior leads to a decrease in bowel movement frequency, slowed intestinal motility, and increased fecal water absorption, resulting in hard, dry stools that are difficult to pass. Intestinal infection (choice B), antibiotic use (choice C), and food allergies (choice D) are less likely to be direct causes of constipation compared to postponing bowel movements.

3. What term is used to refer to generalized wasting of body tissues and malnutrition?

A. Entropion
B. Confabulation
C. Induration
D. Cachexia

Correct answer: D

Rationale: Cachexia is the correct term used to describe the generalized wasting of body tissues, ill health, and malnutrition associated with some chronic diseases. It involves a loss of fat tissue to protect the bones and joints. Clients with cachexia are at risk of pressure ulcers and other complications due to malnutrition and poor health. Entropion refers to an eyelid condition, confabulation is a memory disturbance, and induration is the abnormal hardening of a part of the body.

4. When planning a cultural assessment, what component should the nurse include?

A. Family history
B. Chief complaint
C. Medical history
D. Health practices

Correct answer: D

Rationale: When conducting a cultural assessment, it is essential to include the patient's health practices. Health practices encompass the beliefs, values, and behaviors related to health and illness within a specific cultural context. These practices provide insight into how individuals perceive and manage their health. Family history, chief complaint, and medical history are crucial components of a patient's overall assessment but do not directly relate to a cultural assessment. Focusing on health practices allows the nurse to better understand the patient's cultural background and tailor care to meet their specific needs.

5. In which of these patients would rectal temperatures be measured?

A. Older adult
B. Critically ill patient
C. School-age child
D. Patient receiving oxygen via nasal cannula

Correct answer: B

Rationale: Rectal temperature measurement is preferred in situations where other routes are impractical or when the most accurate measure is necessary, such as in critically ill patients. The rectal route may be chosen due to its reliability in such cases. For older adults, school-age children, and patients receiving oxygen via nasal cannula, rectal temperature measurement is not typically indicated. Other routes like oral, tympanic, or axillary measurements are more commonly used in these populations due to comfort, convenience, and non-invasive nature.
