Question 1 of 5
A patient™s blood pressure elevates to 270/150 mm Hg, and a hypertensive emergency is obvious.
Correct Answer: B
Rationale: In a hypertensive emergency where a patient's blood pressure is extremely elevated (such as 270/150 mm Hg in this case), one of the medications commonly used is a titratable intravenous antihypertensive medication like nicardipine. The maximum dose of nicardipine that should be infused is typically guided by the patient's response to treatment and not a fixed duration of time. Therefore, the correct answer is B, as it highlights the importance of titrating the medication based on the patient's blood pressure response, rather than a specific time frame for infusion. Utilizing the drug at the lowest effective dose is crucial to avoid potential adverse effects, especially in a hypertensive emergency scenario.
Question 2 of 5
The nurse is determining a patient's gastric residual before administering an enteral feeding; the last feeding was 240 mL. The patient will be discharged on enteral feedings. It is important to include in the teaching plan that a residual of more than which amount would indicate delayed gastric emptying (based on the last feeding)?
Correct Answer: A
Rationale: A gastric residual volume of more than 60 mL (or 25% of the last feeding) suggests delayed gastric emptying, which increases the risk of aspiration. The nurse should hold the feeding and reassess if the residual exceeds this threshold. Higher residuals (B, C, D) are not acceptable indicators.
Question 3 of 5
Anticipatory nausea and vomiting associated with chemotherapy occurs:
Correct Answer: C
Rationale: Anticipatory nausea and vomiting occur before chemotherapy administration and are a conditioned response to previous chemotherapy experiences. This psychological response is triggered by cues such as the sight or smell of the treatment environment. It is distinct from acute or delayed nausea and vomiting, which occur during or after chemotherapy. Anticipatory nausea and vomiting can be challenging to manage and often require behavioral interventions or anti-anxiety medications.
Question 4 of 5
Which of the following is/are true for phenolic germicidal agents:
Correct Answer: C
Rationale: Phenolic germicidal agents are commonly used as disinfectants due to their ability to kill microorganisms. Hexachlorophene is one type of phenolic germicidal agent that has been used as a surgical scrub in the past. It has antiseptic properties and can effectively reduce the number of bacteria on the skin, making it suitable for use in sterile environments such as surgical procedures. While phenolic germicidal agents do possess antibacterial properties, they do not typically have topical anesthetic effects like some other types of disinfectants. Additionally, while phenolic agents are used in various dental procedures, they are not specifically used in root canal therapy. The examples provided in the last statement, formocresol, cresantin, and eugenol, are not phenolic germicidal agents but rather dental materials used for different purposes.
Question 5 of 5
A 20-year-old woman who is 15 weeks pregnant is admitted feverish and dehydrated with acute severe asthma associated with a community-acquired pneumonia. She has a history of angioedema following a cephalosporin. Which of the following is not appropriate therapy?
Correct Answer: D
Rationale: Acute asthma and pneumonia in pregnancy require urgent care. IV crystalloids rehydrate, safe and necessary. High FiO2 (40%) supports oxygenation in asthma/pneumonia, appropriate. Nebulized salbutamol, a beta-agonist, relieves bronchospasm, standard and safe. IV hydrocortisone reduces inflammation, suitable. IV gentamicin, an aminoglycoside, treats pneumonia but is inappropriate due to cephalosporin cross-reactivity risk (angioedema history) and fetal ototoxicity concerns, making it unsafe here. Alternative antibiotics (e.g., macrolides) are preferred, prioritizing maternal and fetal safety.
