Question 1 of 5
Which statement indicates a correct understanding of topical drug absorption in a pediatric patient?
Correct Answer: D
Rationale:
Correct
Answer: D
Rationale: Infants wearing plastic-coated diapers are more susceptible to skin absorption due to occlusion by the diaper, leading to increased permeability of the skin and enhanced drug absorption. Plastic-coated diapers create a warm and moist environment that increases skin hydration, facilitating drug penetration. This is important for topical drug absorption in pediatric patients.
Summary:
A: Incorrect. Skin hydration does not solely determine the absorption of water-soluble drugs in pediatric patients.
B: Incorrect. Inflammation typically increases drug absorption rather than decreasing it.
C: Incorrect.
Topical administration may vary in effectiveness depending on factors like skin integrity and age.
D: Correct. The occlusive nature of plastic-coated diapers enhances skin absorption in infants.
E, F, G:
Choices not provided.
Question 2 of 5
A patient takes two medications. Drug A is taken once per day; drug B is taken every 8 hours. Which conclusion about drug A is correct?
Correct Answer: C
Rationale: The correct answer is C: Drug A has a longer half-life than drug B. The half-life of a drug is the time it takes for half of the drug to be eliminated from the body. Since drug A is taken once a day compared to drug B taken every 8 hours, drug A must have a longer half-life to maintain therapeutic levels in the body over a 24-hour period. This indicates that drug A stays in the body longer than drug B.
Choice A is incorrect as the therapeutic range is not determined by the dosing frequency.
Choice B is irrelevant to the dosing frequency of the drugs.
Choice D is incorrect as toxicity is not directly related to dosing frequency.
Question 3 of 5
Which phase of the five-step nursing process is the diagnosis?
Correct Answer: C
Rationale: The correct answer is C: Second. In the nursing process, diagnosis is the second phase where the nurse collects and analyzes data to identify the patient's health problems and needs. This step involves interpreting the information gathered during the assessment phase to develop a nursing diagnosis.
Choice A (Fourth) is incorrect because the fourth phase is planning, where goals and interventions are established.
Choice B (Third) is incorrect because the third phase is planning, which involves setting priorities and outcomes.
Choice D (First) is incorrect because the first phase is assessment, where data is collected.
Question 4 of 5
Which information obtained by the nurse is subjective when a patient experiences adverse effects of a medication?
Correct Answer: C
Rationale: The correct answer is C: Nausea. Subjective information is based on the patient's feelings or perceptions, which cannot be measured or observed externally. Nausea is a symptom reported by the patient, making it subjective. Edema, tachycardia, and cough are objective findings that can be measured or observed by the nurse. Edema refers to visible swelling, tachycardia is an elevated heart rate that can be measured, and cough is a sound that can be heard.
Therefore, these options are objective rather than subjective in nature, making them incorrect choices.
Question 5 of 5
Which factor causes women to experience more problems than men when taking aspirin?
Correct Answer: A
Rationale: The correct answer is A: Gastric acidity. Women tend to have higher gastric acidity than men, leading to increased risk of gastrointestinal issues when taking aspirin. Higher acidity can cause irritation and ulceration in the stomach lining. Levels of hepatic enzyme (
B) and amounts of alcohol dehydrogenase (
C) are not directly linked to aspirin-related issues. Decreased gastric emptying (
D) can also contribute to aspirin-related problems but is not the primary factor.
