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. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: B

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.

3. 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.

4. Where is the Loop of Henle located in the body?

• A. Liver
• B. Kidney
• C. Heart
• D. Ear

Correct answer: B

Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.

5. Which of the following signs or symptoms indicates a possible nutritional deficiency?

• A. Subcutaneous fat at the waist and abdomen
• B. Presence of papillae on the surface of the tongue
• C. Straight arms and legs
• D. Pale conjunctiva

Correct answer: D

Rationale: A client with poor nutritional intake may have pale mucous membranes surrounding the eye, or the conjunctiva. This area should normally be pink, indicating good circulation and a lack of irritation or dryness. Improper nutrition can manifest as numerous signs in the body, including bowed legs, pale mucous membranes, a smooth or beefy tongue, and poor muscle tone. Subcutaneous fat at the waist and abdomen is not a sign of nutritional deficiency but rather of excess fat deposition. The presence of papillae on the surface of the tongue is normal and not indicative of a nutritional deficiency. Straight arms and legs are also typical anatomical features and not specifically related to nutritional deficiencies.
