A nurse is preparing to administer albuterol syrup 1.6 mg PO tid. Available is albuterol 2 mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
Formula:
Volume to administer (mL) = (Desired dose (mg) / Available concentration (mg/mL))
Desired dose = 1.6 mg
Available concentration = 2 mg / 5 mL
Calculate the concentration per mL:
2 mg / 5 mL = 0.4 mg/mL
Volume to administer = 1.6 mg / 0.4 mg/mL
= 4 mL
The nurse should administer 4 mL per dose.

Correct Answer is B
Explanation
A. Standard: While a standard resume format includes basic information about education and experience, it may not effectively address the nurse's multiple moves and varied positions, potentially raising concerns about stability and commitment.
B. Functional: This resume type is most appropriate for the nurse in this situation as it focuses on skills and experiences rather than a chronological work history. This format allows the nurse to highlight relevant skills gained in different positions without emphasizing the frequent changes in employment, which could be beneficial in presenting a cohesive professional narrative.
C. Sequence: This term is less commonly used in resume types and may not provide clarity in presenting qualifications or experiences.
D. Chronological: While this format lists experiences in reverse chronological order, it may draw attention to the frequent changes in positions and locations, which could raise red flags for potential employers regarding the nurse's commitment and stability in a job.
Correct Answer is B
Explanation
A. Poorly coordinated care and nosocomial infections are examples of errors: While poorly coordinated care can lead to adverse events, nosocomial infections are typically classified as healthcare-associated infections rather than errors. Errors generally refer to mistakes made in clinical practice that can lead to harm, whereas nosocomial infections are outcomes that arise from the healthcare environment.
B. As many as 90% of medication errors are preventable: This statement is true and highlights the significant opportunity for improvement in patient safety. Recognizing that a large percentage of medication errors can be prevented underscores the importance of implementing safety protocols, effective communication, and education to reduce the likelihood of errors occurring in clinical practice.
C. Errors of execution are usually intentional and occur because of time or resource constraints: This statement is misleading, as errors of execution typically refer to mistakes made during the performance of a task rather than intentional actions. These errors often occur due to lack of knowledge, skill, or attention rather than being intentional, and they are not solely attributed to time or resource constraints.
D. Medication errors are adverse events: While medication errors can lead to adverse events, not all medication errors result in harm. An adverse event is defined as an injury caused by medical management rather than the underlying condition of the patient, so this statement is not entirely accurate. Medication errors can be classified as near misses or adverse events, depending on whether they resulted in harm to the patient.
