Safe and Effective Care Environment Nclex PN Questions

1. The LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

A. The LPN elevates the head of the bed by at least 30 degrees.
B. If the residual is greater than 200mL, the LPN should not administer the enteral feeding.
C. The LPN should discard the residual before administering the tube feeding.
D. The residual pH level is tested to ensure appropriate placement.

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

2. What should be included in the assessment of a client with a cast?

A. capillary refill, warm toes, no discomfort.
B. posterior tibial pulses, warm toes.
C. moist skin essential, pain threshold.
D. discomfort of the metacarpals.

Correct answer: A

Rationale: When assessing a client with a cast, it is crucial to check for capillary refill to ensure adequate circulation. Warm toes indicate good circulation, while the absence of discomfort suggests the cast is not causing any pain or undue pressure on the client. Therefore, choices B, C, and D are incorrect as they do not address the essential components of assessing a client with a cast.

3. What is a predisposing factor for cancer of the tongue?

A. tobacco use
B. obesity
C. sun exposure
D. eating sweets

Correct answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

4. Which direction given to the nursing assistant is most likely to accomplish the task of getting a urine specimen delivered to the lab immediately after collection?

A. "Make it a stat delivery."?
B. "Please do it as soon as you can after break."?
C. "This client is delirious, and we're worried about urinary sepsis."?
D. "Take this client to the bathroom now and collect a urine specimen from this voiding. Take the specimen to the lab immediately."?

Correct answer: D

Rationale: Effective delegation depends on clear, concise direction that leaves no room for question or interpretation on the part of the one being delegated to. In this scenario, the most appropriate direction is to ensure the urine specimen is collected promptly and delivered to the lab immediately. Choice A is too vague and does not specify the urgency required. Choice B does not emphasize the immediate need for the specimen to be delivered. Choice C introduces unnecessary medical information that is beyond the scope of a nursing assistant and may cause confusion. Therefore, choice D is the correct answer as it provides clear instructions for immediate action without room for misunderstanding.

5. Who is responsible for obtaining the signature from the client on the informed consent?

A. the staff nurse
B. the charge nurse
C. the LPN
D. the physician

Correct answer: D

Rationale: The correct answer is the physician. It is the physician's responsibility to ensure that the client provides informed consent by obtaining their signature. While nurses play a crucial role in the healthcare team, their responsibility lies in verifying that the consent process has been completed correctly and advocating for the client. The staff nurse, charge nurse, and LPN do not have the authority to obtain the client's signature on the informed consent form, as this is within the scope of practice of the physician.
