Pediatric Nursing Practice Questions Questions
Question 1 of 5
Cancer is the second major cause of death in this country. What is the first step toward effective cancer control?
Correct Answer: B
Rationale: The first step toward effective cancer control is changing habits and customs that predispose individuals to cancer. Prevention is key in reducing the incidence of cancer. By addressing factors like smoking, poor diet, lack of physical activity, excessive alcohol consumption, and exposure to carcinogens in the environment, the risk of developing cancer can be significantly reduced. Education and awareness play a crucial role in encouraging individuals to adopt healthier lifestyles and behaviors to minimize their cancer risk. While screening and early detection are also important aspects of cancer control, prevention through lifestyle modifications is the fundamental strategy in reducing the burden of cancer in the population.
Question 2 of 5
When the nurse is reviewing a patient's daily laboratory test results, which of the ff. electrolyte imbalances should the nurse recognize as predisposing the patient to digoxin toxicity?
Correct Answer: A
Rationale: Hypokalemia, or low potassium levels, predisposes the patient to digoxin toxicity because potassium is essential for proper digoxin metabolism. Potassium competes with digoxin for binding sites on sodium-potassium ATPase pumps in the myocardial cells. When potassium levels are low, digoxin binding is increased, leading to an increased risk of digoxin toxicity. Monitoring and correcting hypokalemia are important in patients taking digoxin to reduce the risk of toxicity. Hyperkalemia, on the other hand, can increase the risk of digoxin toxicity by affecting electrophysiological properties of the heart, but hypokalemia is the most significant imbalance predisposing to digoxin toxicity.
Question 3 of 5
If the systolic BP is elevated and the diastolic BP is normal, the nurse recognizes that a patient is most likely to have which type of hypertension?
Correct Answer: B
Rationale: Isolated systolic hypertension is characterized by elevated systolic blood pressure (SBP) with normal diastolic blood pressure (DBP). In this case, if the systolic BP is elevated and the diastolic BP is normal, the nurse would recognize this pattern as indicative of isolated systolic hypertension. This condition is more common in older adults and is associated with aging and stiffening of the arteries. Patients with isolated systolic hypertension are at an increased risk of cardiovascular events, so it is important to monitor and manage their blood pressure appropriately.
Question 4 of 5
Why should the nurse monitor angiotensin converting enzyme inhibitors cautiously in clients with renal or hepatic impairment and in older adults?
Correct Answer: B
Rationale: Angiotensin converting enzyme (ACE) inhibitors are commonly used to manage hypertension and heart failure by blocking the conversion of angiotensin I to angiotensin II. In clients with renal or hepatic impairment, as well as in older adults, the metabolism and excretion of ACE inhibitors may be altered, leading to an increased risk of drug accumulation and potential hypotension. Monitoring these clients cautiously for a sudden drop in blood pressure, especially during the first 1-3 hours after the initial dose, is crucial to prevent complications such as dizziness, lightheadedness, and falls. Adjustments in dosage or frequency may be necessary to ensure the safe and effective use of ACE inhibitors in these populations.
Question 5 of 5
Why should clients who take warfarin (Coumadin) refrain from food items such as green leafy vegetables and soybeans?
Correct Answer: A
Rationale: Clients who take warfarin (Coumadin) should refrain from foods such as green leafy vegetables and soybeans because these foods contain high levels of Vitamin K. Vitamin K plays a crucial role in blood clotting, which may counteract the anti-coagulant effects of warfarin. Therefore, consuming large amounts of Vitamin K-rich foods can reduce the effectiveness of warfarin in preventing blood clots, leading to potential health risks. It is important for clients on warfarin therapy to maintain a consistent intake of Vitamin K in their diet to ensure the medication works effectively.
