Correct Answer: A

Rationale: The correct answer is A: Fruits such as bananas. Bananas are high in potassium, which is essential for various bodily functions like muscle contractions and maintaining fluid balance. Fruits are a natural source of potassium and are easily incorporated into the diet. Milk and yogurt (B) are good sources of calcium, not potassium. Green leafy vegetables (C) are nutritious but may not provide as much potassium as fruits. Nuts and legumes (D) are good sources of protein and healthy fats but are not as rich in potassium as fruits like bananas.

Correct Answer: B

Rationale: The correct answer is B: Hemorrhage. The nurse manager would intervene because hemorrhage is a life-threatening condition requiring immediate attention. Wandering (A), urinary retention (C), and impaired swallowing (D) are important assessments but do not pose the same level of immediate risk as hemorrhage. The nurse manager would prioritize addressing the hemorrhage to ensure the patient's safety and well-being.

Correct Answer: A

Rationale: The correct answer is A. Blood type A is considered the rarest because it is less common in the general population compared to other blood types. The rarity of blood type A is due to the combination of genetic factors that determine blood type. In contrast, blood types B and O are more common in the population, while blood type AB is considered the universal recipient type and is therefore not the rarest. Blood type A is less prevalent, making it the correct answer in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Pericardial friction rub. This is a key diagnostic sign of pericarditis due to the inflammation of the pericardial layers causing a rough, grating sound heard upon auscultation. Precordial pain (A) is a common symptom but not a specific diagnostic sign. Hypotension (C) and rapid/labored respirations (D) are not typically associated with pericarditis. Therefore, the presence of a pericardial friction rub is crucial in confirming the diagnosis of pericarditis.

Correct Answer: B

Rationale: The correct answer is B because the right side weakness indicates a lesion in the left hemisphere of the brain. The brain's motor functions are contralaterally controlled, meaning the left hemisphere controls the right side of the body. Therefore, a right-sided weakness suggests a lesion in the left hemisphere. The other choices are incorrect because expressive aphasia is associated with left hemisphere lesions, judgment of distance and proprioception are more related to parietal lobe lesions, and orientation to time and space is not directly linked to right-sided weakness.
