Nursing Elites

1. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

• A. 2 liters/minute
• B. 4 liters/minute
• C. 6 liters/minute
• D. 8 liters/minute

Correct answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

2. When the healthcare provider is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should they measure?

• A. corner of the mouth to the tragus of the ear
• B. corner of the eye to the top of the ear
• C. tip of the chin to the sternum
• D. tip of the nose to the earlobe

Correct answer: A

Rationale: When selecting the correct size of an oropharyngeal airway, the healthcare provider should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to maintain a clear air passage for exchange. Measuring from the corner of the eye to the top of the ear (Choice B) is inaccurate and not a standard measurement for selecting the size of an oropharyngeal airway. Measuring from the tip of the chin to the sternum (Choice C) is irrelevant to determining the correct size of the airway. Similarly, measuring from the tip of the nose to the earlobe (Choice D) is also incorrect and does not provide the necessary measurement for selecting an oropharyngeal airway size.

3. What dietary alterations should a pregnant client with congenital heart disease expect?

• A. reduced calories and reduced fat
• B. caffeine and sodium restrictions
• C. decreased protein and increased complex carbohydrates
• D. fluid restriction and reduced calories

Correct answer: B

Rationale: In a pregnant client with congenital heart disease, caffeine should be restricted as it can increase heart rate, which is already under stress due to pregnancy. Sodium restrictions may be necessary to prevent fluid retention, which can worsen the client's heart condition. Decreasing calories, fat, protein, or fluid may not be appropriate as these can lead to nutrient deficiencies or inadequate energy intake, which is crucial during pregnancy. Therefore, options A, C, and D are not the expected dietary alterations in the client's diet during pregnancy with congenital heart disease.

4. A nurse is performing suctioning through an adult client's tracheostomy tube. The nurse notes that the client's oxygen saturation is 89% and terminates the procedure. Which action would the nurse take next?

• A. Rechecking the pulse oximetry reading
• B. Calling the respiratory therapist
• C. Calling the healthcare provider
• D. Oxygenating the client with 100% oxygen

Correct answer: D

Rationale: The nurse should monitor the client's heart rate and pulse oximetry during suctioning to assess the client's tolerance of the procedure. Oxygen desaturation to below 90% indicates hypoxemia. If hypoxia occurs during suctioning, the nurse must terminate the procedure and oxygenate the client with 100% oxygen to address the hypoxemia promptly and ensure the client's safety. Rechecking the pulse oximetry reading is important, but the priority is to address the hypoxemia by providing oxygen. Contacting the healthcare provider or respiratory therapist is not necessary at this time as the nurse can manage the hypoxemia with oxygenation. Oxygenating the client with 100% oxygen is the immediate action required in this situation.

5. Which of the following tests is commonly performed on newborns with jaundice?

• A. blood urea nitrogen
• B. magnesium
• C. bilirubin
• D. prolactin

Correct answer: C

Rationale: The correct answer is C: bilirubin. A high bilirubin level is found in newborns with hepatic immaturity, leading to jaundice. Testing bilirubin levels is crucial in diagnosing and monitoring jaundice in newborns. Choices A, B, and D (blood urea nitrogen, magnesium, and prolactin) are not commonly performed tests for evaluating jaundice in newborns. Blood urea nitrogen is a measure of kidney function, magnesium levels are usually checked in metabolic disorders, and prolactin is a hormone related to lactation, none of which are directly relevant to assessing jaundice in newborns.
