Which neurotransmitter mediates the sympathetic response?

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: A

Rationale: The correct answer is A: Vision changes. This is crucial to report immediately because tamoxifen can cause serious eye problems such as retinopathy. Vision changes could indicate a potentially serious adverse reaction that requires prompt medical attention to prevent permanent damage. Headache, hearing loss, and anorexia are not typically associated with tamoxifen use and are less urgent in nature. Reporting vision changes promptly can help prevent irreversible harm and ensure timely intervention.

Correct Answer: A

Rationale: The correct answer is A: Liver. Cancer cells commonly metastasize to the liver due to its rich blood supply, making it an ideal environment for tumor growth. Liver metastasis can occur from various primary cancer sites. The liver filters blood and is susceptible to receiving cancer cells circulating in the bloodstream. Metastasis to the colon (B) is less common as it is typically the primary site for colon cancer. Metastasis to the reproductive tract (C) can occur but is not as common as liver metastasis. White blood cells (D) are a part of the immune system and do not serve as a common site for cancer metastasis.

Correct Answer: C

Rationale: The correct answer is C - the circulating and scrub nurse first assistant. The circulating nurse is responsible for counting needles, sponges, and instruments during the closing of the surgical incision to ensure nothing is left inside the patient. The scrub nurse first assistant also plays a crucial role in this process by assisting in the counting and keeping track of the items used during the procedure. The other choices are incorrect because the surgeon and anesthesiologist (A) are not typically involved in counting items during the surgical closure, the surgeon and the registered (B) may not have the necessary training for accurate counting, and the anesthesiologist and anesthetist (D) are not directly involved in the surgical closing process.

Correct Answer: C

Rationale: Rationale: Choice C is the correct answer because drinking lots of water at night actually helps prevent UTIs by flushing out bacteria from the urinary tract. Holding the urge to urinate (Choice A) can increase the risk of UTIs as bacteria can multiply in stagnant urine. Insertion of instruments and catheters (Choice B) can introduce bacteria, leading to infection. Unhygienic cleaning after defecation (Choice D) can also introduce bacteria to the urinary tract, causing UTIs. Therefore, Choice C is the exception as it does not contribute to the common causes of UTIs.

Correct Answer: D

Rationale: The correct answer is D, as exercise and a weight reduction diet are essential components in managing type 2 diabetes. Exercise helps lower blood glucose levels and improves insulin sensitivity. Weight reduction reduces insulin resistance. Choice A is incorrect because maintaining blood glucose levels between 180-200mg/dl is too high and can lead to complications. Choice B is incorrect as complete smoking cessation is crucial for overall health and diabetes management. Choice C is incorrect because eye examinations should be done annually, not every 2 years, to monitor for diabetic retinopathy. In summary, choice D is the best option as it directly addresses the management of type 2 diabetes.

Correct Answer: A

Rationale: The correct answer is A: Fasciculations. Fasciculations are involuntary muscle twitches commonly seen with neurological conditions like motor neuron disease. In this case, the patient's muscle weakness and frequent muscle twitching indicate possible nerve damage. Chorea (B) is characterized by involuntary, jerky movements, not twitching. Atrophy (C) refers to muscle wasting, not twitching. Neuropathy (D) is a general term for nerve damage and does not specifically describe the muscle twitching seen in this patient.

Correct Answer: B

Rationale: The correct answer is B. Monitoring for signs of restlessness, sweating, and excessive weight loss during thyroid replacement therapy is essential in managing hyperthyroidism. Restlessness can indicate increased metabolic rate, sweating can be due to excessive heat production, and weight loss can be a sign of overactive thyroid function. Providing extra blankets (Choice A) may worsen symptoms of heat intolerance. Balancing activity and rest (Choice C) is important, but not specific to hyperthyroidism. Encouraging activity to prevent constipation (Choice D) is not directly related to managing hyperthyroidism.
