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: Rationale: The correct answer is B because the kidneys do not reabsorb carbon dioxide to regulate acid-base balance. Carbon dioxide is mainly regulated by the lungs through respiration. The kidneys regulate acid-base balance by excreting hydrogen ions, reabsorbing or excreting bicarbonate (HCO3-) into the blood, and retaining or excreting hydrogen ions. Reabsorbing carbon dioxide is not a mechanism utilized by the kidneys for acid-base balance. Choices A, C, and D are correct mechanisms involved in acid-base balance regulation by the kidneys.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be observed or measured by others. In this case, choice C is correct because the patient describing excitement about discharge is personal and based on the patient's feelings or perceptions. This is subjective data because it is based on the patient's own experiences and emotions. Choices A and B are incorrect because patient's temperature and wound appearance are objective data that can be measured or observed by the nurse. Choice D is also incorrect as patient pacing the floor is an observable behavior, making it objective data. Therefore, choice C is the correct answer as it represents subjective data in the context of the assessment.

Correct Answer: A

Rationale: Rationale: - The correct answer is A, "Have you been exposed recently to anyone with an infection?" because it helps assess potential sources of infection causing the low-grade fever and other symptoms. - Choice B is irrelevant as the client's current sore throat is not the main concern. - Choice C and D do not address the potential infectious etiology of the symptoms. - Overall, assessing recent exposure to infections is crucial in identifying possible sources of the client's symptoms.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.
