Nursing Elites

1. Which of the following microorganisms are considered normal body flora?

• A. staphylococcus on the skin
• B. streptococcus in the nares
• C. candida albicans in the vagina
• D. pseudomonas in the blood

Correct answer: A

Rationale: Staphylococcus is considered normal body flora as it is commonly found on the skin, being a part of the normal microbiota. While streptococcus in the nares can be part of the normal flora of the upper respiratory tract, it is not as common or as widespread as staphylococcus on the skin. Candida albicans in the vagina is not considered normal flora; it is a common opportunistic pathogen in the vagina. Pseudomonas in the blood is also not considered normal body flora; pseudomonas is not typically found in the blood as part of the normal microbiota.

2. When are pressure ulcers most likely to occur?

• A. when clients are left in one position in bed for extended periods of time.
• B. when clients are underweight.
• C. when clients are overweight.
• D. only in underweight and overweight clients.

Correct answer: A

Rationale: Pressure ulcers usually occur over bony prominences and are caused by decreased circulation. The client who is left in one position in bed for extended periods of time is more prone to decreased circulation to an area of the body and to acquiring a pressure ulcer. Choices B and C are incorrect as pressure ulcers are not exclusive to underweight or overweight clients. The key factor is prolonged pressure on the skin, not the weight of the client. Therefore, the correct answer is that pressure ulcers are most likely to occur when clients are immobilized in one position for extended periods of time.

3. 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.

4. In an obstetrical emergency, which of the following actions should the nurse perform first after the baby delivers?

• A. Place extra padding under the mother to absorb blood from the delivery.
• B. Cut the umbilical cord using sterile scissors.
• C. Suction the baby's mouth and nose.
• D. Wrap the baby in a clean blanket to preserve warmth.

Correct answer: C

Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.

5. The LPN is preparing to clean a client's PEG tube.The following tasks should the nurse perform EXCEPT?

• A. Gently remove crusty drainage from the site.
• B. Pull the tube in multiple directions to ensure it is secure.
• C. Thoroughly dry the skin around the tube site with a clean towel.
• D. Use mild soap to clean around the tube site.

Correct answer: B

Rationale: When cleaning a client's PEG tube, the nurse should perform tasks that focus on gentle cleaning and avoiding potential irritants. Choice A is correct as gently removing crusty drainage helps maintain hygiene. Choice C is important to prevent skin irritation and infection. Choice D is appropriate for cleaning the area. Choices B and D are incorrect. Choice B is incorrect because pulling the tube in multiple directions can lead to dislodgement or injury. Choice B is incorrect as talcum powder may irritate the stoma, and it is generally not recommended near PEG tubes.
