Which of the following responses indicates sympathetic nervous system function?
- A. Tachycardia, dilated pupils
- B. Hypoglycaemia, headache
- C. Increased peristalsis, abdominal cramping
- D. Pupil constriction, bronchoconstriction
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.

What is the nurse’s primary legal responsibility when implementing nursing interventions?
- A. Ensure client safety
- B. Follow physician orders precisely
- C. Document care comprehensively
- D. Provide client-centered education
Correct Answer: A
Rationale: The correct answer is A: Ensure client safety. This is the nurse's primary legal responsibility as it aligns with the ethical principle of beneficence, prioritizing the well-being and safety of the client. Ensuring client safety is essential to prevent harm and promote positive health outcomes. Following physician orders precisely (B) is important but not the primary legal responsibility of the nurse. Documenting care comprehensively (C) is crucial for accountability and continuity of care but is not the primary legal responsibility. Providing client-centered education (D) is essential for empowering clients but is not the primary legal responsibility in terms of legal accountability and duty of care.
A patient asks how to avoid lung cancer. The following are risk factors, except:
- A. Exposure to passive smoke
- B. Crowded living conditions
- C. Air pollution
- D. Diet low in fruits and vegetables
Correct Answer: B
Rationale: Step 1: Crowded living conditions do not directly increase the risk of lung cancer.
Step 2: Passive smoke (choice A) and air pollution (choice C) contain carcinogens linked to lung cancer.
Step 3: Diet low in fruits and vegetables (choice D) may lead to poor immune function, potentially impacting cancer risk.
Step 4: In summary, crowded living conditions do not contribute to lung cancer risk compared to the other choices.
Mrs. Zeno continues to become a weaker despite .treatment with neostigmine. Edrophonium HCL is ordered:
- A. For its synergestic effect
- B. Because of the client's resistance to
- C. To rule out cholinergic crisis Neostigmine
- D. To confirm the diagnosis of myasthenia
Correct Answer: C
Rationale: The correct answer is C: To rule out cholinergic crisis Neostigmine. Edrophonium HCL is a short-acting cholinesterase inhibitor used to differentiate between myasthenic crisis and cholinergic crisis, as both conditions present similarly with muscle weakness. Administering edrophonium HCL will help determine if the patient's worsening weakness is due to excessive cholinergic stimulation from neostigmine (cholinergic crisis) or inadequate acetylcholine at the neuromuscular junction (myasthenic crisis). This step is crucial for proper management, as treating cholinergic crisis with more cholinesterase inhibitors like neostigmine can worsen symptoms.
Incorrect choices:
A: For its synergistic effect - Edrophonium HCL does not have a synergistic effect with neostigmine.
B: Because of the client's resistance to - Resistance to neostigmine is not a reason to administer edrophonium H
Emil, just had a thyroidectomy this morning. Upon awakening, he complains of circumoral tingling, has a positive Chvostek’s sign and positive Trousseau’s sign. Nurse Ofel assesses this to be an indication of:
- A. Overstimulation of the parathyroid hormone
- B. Insufficient iodine intake
- C. inadvertent removal of the parathyroid
- D. Overuse of radioactive iodine gland
Correct Answer: A
Rationale: Rationale: The correct answer is A, overstimulation of the parathyroid hormone. After a thyroidectomy, there is a risk of unintentional damage to the parathyroid glands, leading to hypoparathyroidism. Circumoral tingling, positive Chvostek’s sign, and positive Trousseau’s sign are classic signs of hypocalcemia resulting from parathyroid insufficiency. Choices B, C, and D are incorrect because they do not explain the specific symptoms observed in Emil, which are indicative of low calcium levels due to parathyroid dysfunction.
Which food choice contains the highest kilocalorie?
- A. Apple
- B. Chicken
- C. Bacon
- D. Bread
Correct Answer: C
Rationale: The correct answer is C: Bacon. Bacon contains the highest kilocalorie among the given choices due to its high fat content. Fat provides 9 kilocalories per gram, while carbohydrates (like in bread and apple) provide 4 kilocalories per gram and protein (like in chicken) provides 4 kilocalories per gram. Bacon, being high in fat, has more kilocalories compared to the other choices.
Summary:
A: Apple - Low in fat, primarily consists of carbohydrates, hence lower in kilocalories.
B: Chicken - Contains protein, lower in kilocalories compared to fat, hence not the highest kilocalorie choice.
D: Bread - Mainly consists of carbohydrates, lower in kilocalories compared to fat, making it not the highest kilocalorie choice.
