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.

Correct Answer: C

Rationale: Rationale: 1. Loratadine is typically dosed once daily, not twice daily, for allergic rhinitis. 2. Taking it twice daily may increase the risk of side effects without added benefit. 3. The client's dosing schedule reflects a misunderstanding of the medication regimen. 4. Option A is incorrect because loratadine is available in 10mg tablets. 5. Option B is incorrect as loratadine can be taken with or without food. 6. Option D is incorrect as Claritin is a common trade name for loratadine.

Correct Answer: A

Rationale: The correct answer is A: Expressive aphasia and paralysis on the right side of the body. In a right-handed person, the left side of the brain controls language and right-sided motor function. A stroke affecting the left side of the cortex would lead to expressive aphasia due to damage to Broca's area, causing difficulty in speaking and forming words. Paralysis on the right side of the body would result from damage to the motor cortex in the left hemisphere. Choices B, C, and D are incorrect because they do not align with the typical deficits seen in a person with a stroke affecting the left side of the cortex in a right-handed individual.

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.
