1. 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.

2. 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.

3. 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.

4. When a physician removes a chest tube, which type of dressing is recommended to be placed over the site?

• A. transparent dressing
• B. colloidal dressing
• C. petrolatum gauze
• D. nonadherent dressing

Correct answer: C

Rationale: Petrolatum gauze is recommended to be placed over the site when a physician removes a chest tube because it forms an airtight seal, helping prevent air from entering the pleural space. This airtight seal is crucial to avoid complications such as a pneumothorax. Transparent dressing is not ideal for this purpose as it may not provide a sufficient seal due to its design. Colloidal dressing and nonadherent dressing are also not suitable for chest tube removal sites as they do not offer the same level of protection against air leakage and may not provide the necessary sealing properties.

5. A client with an ileus is placed on intestinal tube suction. Which of the following electrolytes is lost with intestinal suction?

• A. calcium
• B. magnesium
• C. potassium
• D. sodium chloride

Correct answer: D

Rationale: When a client with an ileus is placed on intestinal tube suction, the primary electrolyte lost is sodium chloride. Duodenal intestinal fluid contains potassium (K+), sodium (Na+), and bicarbonate. Suctioning is done to remove excess fluids, leading to a decrease in the client's sodium chloride levels. Therefore, options A, B, and C are incorrect as calcium, magnesium, and potassium are not the primary electrolytes lost during intestinal suction in a client with an ileus.
