Nursing Elites

1. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

2. A nonimmunized child appears at the clinic with a visible rash. Which of the following observations indicates the child may have rubeola (measles)?

• A. Small blue-white spots are visible on the oral mucosa.
• B. The rash begins on the trunk and spreads outward.
• C. There is low-grade fever.
• D. The lesions have a "teardrop-on-a-rose-petal"? appearance.

Correct answer: A

Rationale: The presence of small blue-white spots on the oral mucosa, known as Koplik's spots, is characteristic of measles (rubeola) infection. These spots typically appear on the buccal mucosa opposite the second molars, 1-2 days before the rash onset, and last until 2 days after the rash appears. While Koplik's spots are pathognomonic for measles, their absence does not rule out the diagnosis. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because the rash pattern, presence of low-grade fever, and characteristic appearance of lesions are not specific indicators of measles infection.

3. What would a healthcare professional expect to observe while assessing the growth of children during their school-age years?

• A. Decreasing amounts of body fat and muscle mass
• B. Little change in body appearance from year to year
• C. Progressive height increase of 4 inches each year
• D. Yearly weight gain of about 5.5 pounds per year

Correct answer: D

Rationale: During school-age years, children typically gain about 5.5 pounds per year and increase in height by about 2 inches annually. This steady growth pattern is expected between ages 2 to 10 years. Choice A is incorrect as children at this stage are expected to gain weight and grow in height. Choice B is incorrect as there should be noticeable changes in body appearance due to growth. Choice C is incorrect as a progressive height increase of 4 inches each year is not typical during the school-age years.

4. A victim of a gunshot wound to the abdomen has been admitted to the hospital, accompanied by a police officer. When questioned, the officer states that the patient is a suspect in a homicide, which occurred as part of the same incident. A small child was killed as the result of a stray bullet. The patient is combative, yells that he's in pain and demands medication. What is your most appropriate response?

• A. Tell him you'll take care of him after your other patients
• B. Reinforce restraints
• C. Perform a pain assessment and administer pain medication
• D. Ask the officer for more details of the incident

Correct answer: C

Rationale: The most appropriate and caring response is to perform a pain assessment and administer the pain medication that has been ordered. Regardless of personal feelings about any given situation, the nurse's responsibility is to provide unbiased, appropriate, and supportive care, as stated in the American Nurses Association (ANA) Code of Ethics. Choice A is not appropriate as it disregards the patient's immediate need for pain relief. Choice B may escalate the situation and is not the priority in this case. Choice D is not the immediate action needed to address the patient's pain and distress.

5. Which risk factor places patients and residents at the greatest risk for falls?

• A. Old age
• B. Middle age
• C. Pneumonia
• D. COPD

Correct answer: A

Rationale: Old age is a significant risk factor for falls as elderly individuals are more prone to falls due to factors like decreased balance, muscle strength, and vision. Middle age is less associated with falls compared to old age. Pneumonia and COPD are medical conditions that are not direct risk factors for falls, unlike aging which significantly increases the risk of falls.
