Correct Answer: D

Rationale: The correct answer is D because monitoring for signs of infection, air embolus, and leakage/puncture are crucial in caring for a patient with a central venous line to prevent serious complications. Infections can lead to sepsis, air embolus can cause respiratory distress, and leakage/puncture can result in hemorrhage or damage to surrounding tissues. A: While a complete blood count and electrolytes may be important for monitoring the patient's overall health, they are not specific to the central venous line care. B: Regular chest x-rays are not necessary unless there are specific indications of line malposition or complications. C: Continuous infusion at a keep-vein-open rate is a standard practice but does not address the critical aspects of central line care mentioned in option D. Therefore, monitoring for signs of infection, air embolus, and leakage/puncture is the most essential component of the plan of care for a patient with a central venous line.

Correct Answer: A

Rationale: The correct answer is A: Norepinephrine. Norepinephrine is the primary neurotransmitter that mediates the sympathetic response. It is released by sympathetic nerve endings and acts on adrenergic receptors in various target organs to initiate the "fight or flight" response. Prostaglandin, acetylcholine, and serotonin do not directly mediate the sympathetic response and are involved in different physiological processes.

Correct Answer: A

Rationale: The correct answer is A: Post-trauma syndrome related to being attacked. This diagnosis accurately reflects the client's symptoms of reliving the traumatic event, crying uncontrollably, and expressing fear. "Post-trauma syndrome" encompasses the psychological and emotional distress following a traumatic event. Choice B: Psychological overreaction simplifies the client's experience and does not capture the severity or ongoing nature of the trauma symptoms. Choice C: Needs assistance coping with attack is vague and does not provide a specific diagnosis or acknowledge the clinical presentation of the client. Choice D: Mental distress related to being attacked is too broad and does not specify the specific syndrome or symptoms experienced by the client.

Correct Answer: B

Rationale: The correct answer is B: Purplish discoloration of hands and feet. Hand-foot syndrome in sickle cell anemia is characterized by pain, swelling, and purplish discoloration of the hands and feet due to vaso-occlusive crisis. Unequal growth of fingers and toes (A), webbing between fingers and toes (C), and deformities of wrists and ankles (D) are not typical findings associated with hand-foot syndrome in sickle cell anemia.

Correct Answer: D

Rationale: The correct answer is D: Human papilloma virus (HPV) infection at age 32. HPV is a known risk factor for cervical cancer as it can lead to cellular changes in the cervix. Here's the rationale: 1. HPV is a sexually transmitted infection that can cause abnormal cell growth in the cervix. 2. Persistent HPV infection is a major risk factor for developing cervical cancer. 3. Age 32 is within the typical age range for HPV infection and the development of cervical cancer. 4. Choices A, B, and C are unrelated to the primary risk factor for cervical cancer, which is HPV infection.
