A nurse is caring for a group of clients on an infectious disease unit.
The nurse should wear an N95 respirator mask when caring for a client who has which of the following disorders?
Scabies.
Mycoplasmal pneumonia.
Tuberculosis.
Scarlet fever.
The Correct Answer is D
Choice D rationale:
Performing strict hand washing before and after the care of each client is the most effective method to reduce healthcare-associated infections (HAIs) Hand hygiene is a critical component of infection prevention and control. Proper hand washing helps eliminate the spread of pathogens from one patient to another, as well as from patients to healthcare providers and vice versa. The rationale behind this choice lies in the fact that many infections are transmitted via contaminated hands. By washing hands thoroughly with soap and water or using hand sanitizer, healthcare providers can significantly reduce the risk of HAIs. It is essential to perform hand hygiene before and after every patient contact, after exposure to body fluids, and after touching patient surroundings.
Choice A rationale:
Providing small bedside bags to dispose of used tissues addresses a specific aspect of infection control (proper disposal of contaminated items) While this practice is important, it does not cover the comprehensive approach of standard precautions, which includes various infection prevention measures. Using bedside bags for tissue disposal is not a substitute for strict hand hygiene or the use of personal protective equipment.
Choice B rationale:
Instructing staff members to wear masks while providing care is important in specific situations, such as when dealing with patients on airborne precautions. However, it does not cover all aspects of infection prevention. Masks are just one component of personal protective equipment (PPE) and are used in addition to other measures like gloves and gowns, depending on the type of isolation precautions required for a particular patient. Moreover, the most crucial aspect of infection prevention remains hand hygiene.
Choice C rationale:
Administering antibiotics as ordered is a medical intervention for treating infections, not a preventive measure to reduce healthcare-associated infections (HAIs) While appropriate use of antibiotics is essential in the treatment of bacterial infections, it does not address the broader issue of preventing the spread of infections within healthcare settings. In fact, overuse or misuse of antibiotics can lead to antibiotic resistance, making infections harder to treat in the future.

Correct Answer is B
Explanation
Choice A rationale:
Obtaining the blood pressure first thing in the morning is not the most critical factor in accurately measuring blood pressure. Blood pressure can vary throughout the day due to various factors, and it is essential to use the appropriate technique and equipment at any time of the day.
Choice B rationale:
Using the appropriate size cuff for the client is crucial in obtaining an accurate blood pressure reading. If the cuff is too small, it can lead to falsely elevated blood pressure readings, while a cuff that is too large can result in falsely lowered readings. This is because cuff size affects the pressure applied to the artery during measurement.
Choice C rationale:
Ensuring that the client is relaxed and comfortable prior to obtaining the blood pressure is important but not the most critical factor. Anxiety or discomfort can temporarily elevate blood pressure, so it's essential to create a calm and comfortable environment for the client. However, using the correct cuff size is still more critical for accurate measurements.
Choice D rationale:
Removing clothing from the arms before obtaining blood pressure is not the most important action. While it is generally recommended to expose the client's arm for proper cuff placement, it is secondary to using the appropriate cuff size. The cuff should be placed directly on the skin or over a thin layer of clothing, but this step should not take precedence over cuff size selection.
Correct Answer is ["7.1"]
Explanation
The correct answer is7.1 fl oz.
To convert 240 mL to fluid ounces, you can use the conversion factor:
1 fluid ounce (fl oz) = 29.5735 mL.
Calculation steps:
240 mL × ( 1 fl oz 29.5735 mL ) ≈ 8.12 fl oz . 240mL×( 29.5735mL 1fl oz ) ≈ 8.12fl oz. Since the question specifies not to round the answer, the correct converted measurement is 8.12 fl oz. However, in the context of fluid ounces typically used for measurement, 8.12 fl oz should be rounded to 8.1 fl oz or 7.1 fl oz (considering one decimal place)
