Correct Answer: A

Rationale: The correct answer is A: Pregnancy. During pregnancy, the need for iron increases significantly to support the growth of the fetus and to prevent maternal anemia. Iron is essential for the production of hemoglobin and for oxygen transport in the blood. In contrast, infants require iron for rapid growth and development, making choice B partially correct. Choice C (Old age) and choice D (Male reproductive years) are incorrect as the need for iron typically decreases in old age and remains relatively stable during male reproductive years.

Correct Answer: B

Rationale: The correct answer is B: Severe tenderness and swelling in the scrotum. Epididymitis is characterized by inflammation of the epididymis, causing symptoms such as severe tenderness and swelling in the scrotum. Choice A is incorrect as burning and pain on urination are more indicative of a urinary tract infection. Choice C, foul-smelling ejaculate and severe scrotal swelling, is not commonly associated with epididymitis. Choice D, foul-smelling urine and pain on urination, may indicate a urinary tract infection but are not specific to epididymitis.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In hemodialysis, potassium levels can be elevated due to impaired renal excretion. High potassium can lead to muscle weakness and numbness. The client's K level of 5.9 mEq/L is above the normal range (3.5-5.0 mEq/L), confirming hyperkalemia. Na, Cl, and Ca levels are within normal limits, ruling out hypernatremia, hypochloremia, and hypocalcemia as the client's primary electrolyte imbalance. Monitoring and managing hyperkalemia are crucial to prevent life-threatening complications like cardiac arrhythmias.

Correct Answer: B

Rationale: The correct answer is B: Compatible blood and tissue types. This is crucial to minimize the risk of rejection and ensure a successful transplant. Matching blood and tissue types help prevent the recipient's immune system from attacking the new organ. Blood relationship (A) is not as important as compatibility. Sex and size (C) are important considerations for certain transplants but not the most crucial factor. Need (D) is relevant but does not outweigh the importance of compatibility to ensure a successful transplant.

Correct Answer: A

Rationale: Rationale: 1. By approaching the patient from the other side, the nurse can assess if the patient has a visual field deficit. 2. This step helps determine if the lack of response is due to a sensory issue. 3. It allows the nurse to rule out unilateral neglect or hemianopsia. 4. Walking to the other side is a basic assessment technique to evaluate visual and sensory deficits in poststroke patients. Other Choices: B. Speaking more loudly and clearly may not address the potential sensory issues the patient is experiencing. C. Waving fingers in front of the patient's face does not provide a comprehensive assessment of visual field deficits. D. Using a picture may be helpful, but addressing the potential visual field deficit should be prioritized first.
