Nursing Elites

1. The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?

• A. Inflammation of the mucous membrane & bronchospasm
• B. Increased mucus production and bronchoconstriction
• C. Allergic reactions and hyperventilation
• D. Airway narrowing and decreased lung capacity

Correct answer: A

Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.

2. A client is admitted to a medical unit with the diagnosis of gastritis and chronic heavy alcohol abuse. What should the nurse administer to prevent the development of Wernicke's syndrome?

• A. Lorazepam (Ativan)
• B. Famotidine (Pepcid)
• C. Thiamine (Vitamin B1)
• D. Atenolol (Tenormin)

Correct answer: C

Rationale: Thiamine supplementation is critical in preventing Wernicke's syndrome, especially in clients with chronic alcohol use. Wernicke's syndrome is a neurological disorder caused by thiamine deficiency. Lorazepam is a benzodiazepine used for anxiety and not for preventing Wernicke's syndrome. Famotidine is an H2 blocker used to reduce stomach acid production but does not prevent Wernicke's syndrome. Atenolol is a beta-blocker used for hypertension and angina, not for preventing Wernicke's syndrome.

3. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?

• A. 12.5
• B. 5
• C. 10
• D. 20

Correct answer: B

Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.

4. The healthcare provider is completing a head-to-toe assessment for a client admitted for observation after falling out of a tree. Which finding warrants immediate intervention by the healthcare provider?

• A. Sluggish pupillary response to light
• B. Clear fluid leaking from the nose
• C. Complaint of severe headache
• D. Periorbital ecchymosis of the right eye

Correct answer: B

Rationale: Clear fluid leaking from the nose is concerning for cerebrospinal fluid leakage, which is a medical emergency requiring immediate intervention. Sluggish pupillary response to light may indicate neurological issues but is not as urgent as CSF leakage. Complaint of severe headache is important but not as critical as the possibility of CSF leakage. Periorbital ecchymosis of the right eye could be indicative of trauma but does not pose an immediate threat to the patient's life.

5. Which client’s vital signs indicate increased intracranial pressure (ICP) that the nurse should report to the healthcare provider?

• A. P 70, BP 120/60 mmHg; P 100, BP 90/60 mmHg; rapid respirations.
• B. P 55, BP 160/70 mmHg; P 50, BP 194/70 mmHg; irregular respirations.
• C. P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations.
• D. P 110, BP 130/70 mmHg; P 100, BP 110/70 mmHg; shallow respirations.

Correct answer: C

Rationale: Choice C is the correct answer. The vital signs presented (P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations) indicate increased intracranial pressure (ICP), which can be a serious condition requiring immediate medical attention. Kussmaul respirations are deep and labored breathing patterns associated with metabolic acidosis and can be a late sign of increased ICP. Choices A, B, and D do not demonstrate vital sign patterns consistent with increased ICP. Choice A shows variations in blood pressure and pulse rate but does not provide a clear indication of increased ICP. Choice B displays fluctuations in blood pressure and pulse rate with irregular respirations, but these vital signs do not specifically suggest increased ICP. Choice D presents relatively stable vital signs with shallow respirations, which do not align with the typical vital signs seen in increased ICP.
