Which of the following responses indicates sympathetic nervous system function?

Correct Answer: A

Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action. Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.

Correct Answer: A

Rationale: The correct answer is A: “You’ll need more insulin when you exercise or increase your food intake.” In type 1 diabetes, exercise and increased food intake can lead to increased glucose levels, requiring more insulin to maintain blood sugar control. Increasing physical activity can enhance insulin sensitivity, necessitating adjustments in insulin dosage. Choices B, C, and D are incorrect as they do not align with the physiological response in type 1 diabetes. B suggests needing less insulin when exercising, which is inaccurate as physical activity can lower blood sugar levels. C implies needing less insulin with increased food intake, which is incorrect as more food can lead to higher glucose levels. D suggests needing more insulin when decreasing food intake, which is not necessarily true as lower food intake can result in lower glucose levels.

Correct Answer: D

Rationale: The correct answer is D: Evaluation. After implementing nursing interventions based on priority diagnoses, the nurse must evaluate the effectiveness of these interventions to determine if the desired outcomes have been achieved. Evaluation is crucial to assess the progress, make necessary modifications, and ensure the effectiveness of the care provided. Assessment (A) is already completed before interventions are carried out. Planning (B) involves developing a care plan based on assessment findings. Implementation (C) is the actual carrying out of the interventions. Therefore, the next step after implementing nursing interventions is to evaluate their effectiveness.

Correct Answer: D

Rationale: The correct answer is D: It will increase the need for insulin. Infections like sinusitis and otitis media can lead to increased stress on the body, causing insulin resistance and higher blood sugar levels. This leads to an increased demand for insulin to regulate blood sugar levels effectively. Therefore, the diabetic client's need for insulin will likely increase in this scenario. Incorrect choices: A: It will have no effect - Incorrect because infections and fever can impact insulin requirements. B: It will cause wide fluctuations in the need for insulin - Incorrect as infections generally lead to increased insulin needs, not fluctuations. C: It will decrease the need for insulin - Incorrect as infections and fever typically increase insulin requirements due to increased stress on the body.

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. Lung cancer causes the most deaths in women due to its high mortality rate. It is often diagnosed at an advanced stage, leading to poorer outcomes. Breast cancer, although common, has a lower mortality rate compared to lung cancer. Brain cancer is relatively rare in comparison. Colon and rectal cancer, while significant, do not surpass lung cancer in terms of causing the most deaths in women.

Correct Answer: C

Rationale: The correct answer is C: 15 to 20 g of a fast-acting carbohydrate such as orange juice. In this scenario, the client is experiencing hypoglycemia, which can lead to confusion and abnormal behavior. Administering fast-acting carbohydrates like orange juice will help quickly raise the blood sugar levels. This is the first-line treatment for conscious patients with hypoglycemia. Choice A (I.M. or subcutaneous glucagon) is used for unconscious patients or when oral intake is not possible. Choice B (I.V. bolus of dextrose 50%) is too aggressive for a conscious patient and may lead to complications. Choice D (10 U of fast-acting insulin) would further lower the blood sugar levels and worsen the situation. Administering fast-acting carbohydrates is the safest and most effective approach for conscious patients with hypoglycemia to quickly raise their blood sugar levels and resolve their symptoms.

Correct Answer: B

Rationale: The correct answer is B. This statement shows an understanding of reducing HIV transmission by promoting harm reduction strategies like needle exchange programs, which help prevent sharing of contaminated needles. This approach is evidence-based and effective in reducing the spread of HIV among injection drug users. Choice A is incorrect because breastfeeding by HIV-positive mothers can transmit the virus to infants. Choice C is incorrect as birth control pills do not protect against HIV, only against pregnancy. Choice D is incorrect as natural skin condoms do not provide the same level of protection against HIV as latex condoms do.

Correct Answer: B

Rationale: The correct answer is B: Ineffective airway clearance related to obstruction by a tumor or secretions. This takes highest priority as compromised airway can lead to respiratory distress and potential respiratory failure. Maintaining clear airways is essential for oxygenation and ventilation. Choices A, C, and D are important but do not pose immediate life-threatening risks compared to compromised airway. Disturbed body image, anxiety, and imbalanced nutrition can be addressed once the airway clearance is stabilized.

Correct Answer: B

Rationale: Step 1: High cholesterol levels contribute to the buildup of plaque in arteries, leading to atherosclerosis and increasing the risk of coronary artery disease. Step 2: Atherosclerosis can result in a blockage of blood flow to the heart, causing a myocardial infarction (MI). Step 3: Age is a risk factor for CAD but not directly linked to MI development. Step 4: Medication usage may impact risk factors but is not a direct cause of MI. Step 5: Gender can influence risk but is not the primary factor in MI development.
