Correct Answer: A

Rationale: Step 1: Regular aerobic exercise helps lower blood pressure by improving heart health and circulation. Step 2: Exercise reduces stress and promotes weight loss, factors that contribute to hypertension control. Step 3: Alcohol consumption can raise blood pressure and should be limited or avoided. Step 4: Smoking and using low-tar cigarettes can still raise blood pressure and have other negative health effects. Step 5: Daily multivitamin supplements do not directly impact blood pressure control.

Correct Answer: A

Rationale: The correct answer is A, below 70mg/dl, for a hypoglycemic client. Hypoglycemia is defined as low blood glucose levels, typically below 70mg/dl. Symptoms of hypoglycemia include confusion, sweating, shakiness, and palpitations. Treating hypoglycemia involves providing the client with a fast-acting source of glucose to raise their blood sugar levels quickly. Choices B, C, and D are incorrect as they indicate normal or elevated blood glucose levels, which are not characteristic of hypoglycemia. It is crucial for the nurse to recognize and promptly address hypoglycemia to prevent potential complications.

Correct Answer: C

Rationale: The correct answer is C because subjective data refers to information provided by the patient, such as their feelings, perceptions, and symptoms. In this case, the patient describing excitement about discharge is subjective as it is based on their personal experience. The other options (A, B, D) are objective data as they can be measured or observed directly without interpretation. The patient's temperature (A) and wound appearance (B) are physical observations, while the patient pacing the floor (D) is a behavior that can be observed. Therefore, only choice C fits the definition of subjective data in a nursing assessment.

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: 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.
