1. A healthcare professional is assessing a patient's skin. Which patient is most at risk for impaired skin integrity?
- A. A patient who is afebrile
- B. A patient who is diaphoretic
- C. A patient with strong pedal pulses
- D. A patient with adequate skin turgor
Correct answer: B
Rationale: Excessive moisture on the skin, as seen in a diaphoretic patient, can lead to impaired skin integrity. Diaphoresis softens epidermal cells, promotes bacterial growth, and can cause skin maceration. Afebrile status, strong pedal pulses, and adequate skin turgor are not directly associated with an increased risk of impaired skin integrity. Afebrile indicates the absence of fever, not a risk to skin integrity. Strong pedal pulses suggest good circulation, which is beneficial for skin health. Adequate skin turgor is a sign of good hydration and skin elasticity, indicating a lower risk of impaired skin integrity.
2. A nurse prepares an injection of morphine to administer to a client who reports pain but asks a second nurse to give the injection because another assigned client needs to use a bedpan. Which of the following actions should the second nurse take?
- A. Offer to assist the client who needs the bedpan.
- B. Administer the injection the other nurse prepared.
- C. Prepare another syringe and administer the injection.
- D. Tell the client who needs the bedpan to wait while the nurse gives someone else medication.
Correct answer: C
Rationale: The second nurse should prepare a new syringe and administer the medication to ensure proper and timely pain management. Administering another nurse's medication without preparation could lead to errors. Choice A is not the priority as the medication administration should take precedence. Choice B is not recommended as the second nurse should not administer medication prepared by another nurse. Choice D is inappropriate as patient needs should not be compromised for medication administration to another client.
3. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?
- A. Assess the client for a gag reflex
- B. Measure the pH of the gastric aspirate
- C. Place the end of the NG tube in water to observe for bubbling
- D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water
Correct answer: B
Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.
4. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?
- A. pH below 7.3
- B. Potassium of 5.0
- C. HCT of 60
- D. PaO2 of 79%
Correct answer: C
Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
5. When caring for a client with diarrhea due to Shigella, which of the following precautions should the nurse take?
- A. Wash hands before and after contact with the client
- B. Wear a surgical mask
- C. Use a face shield
- D. Wear a gown and gloves only
Correct answer: A
Rationale: The correct precaution for Shigella infection is to wash hands thoroughly before and after contact with the client. Shigella is transmitted through the fecal-oral route, so hand hygiene is crucial in preventing its spread. Wearing a surgical mask or face shield is not necessary for Shigella as it is not primarily transmitted through respiratory droplets. While wearing a gown and gloves is important for standard precautions, the key precaution specific to Shigella is proper hand hygiene.
