A client arrives at a hurricane disaster medical area seeking treatment for diarrhea.

Which source of contamination should the nurse consider when interviewing the client about exposure?

• A radial pulse is the pulse felt at the wrist, where the radial artery runs along the thumb side of the forearm. It is one of the most common sites for measuring a person's heart rate.
• To measure a radial pulse, the examiner should place two or three fingers over the radial artery, just below the wrist crease, and apply gentle pressure until a pulsation is felt. The examiner should not use the thumb, as it has its own pulse and may interfere with the accuracy of the measurement. The examiner should count the number of beats for 15, 30, or 60 seconds, depending on the regularity and rate of the pulse.
• In the picture, the unlicensed assistive personnel (UAP) is using the thumb to measure the radial pulse, which is incorrect. The practical nurse (PN) should demonstrate the correct pulse site to the UAP and explain why using the thumb is not appropriate. This will help to ensure that the UAP obtains an accurate and reliable pulse rate for the client.

Therefore, option C is the correct answer, while options A, B, and D are incorrect.

Option A is incorrect because instructing the UAP to report any abnormal findings does not address the error in technique.

Option B is incorrect because reminding the UAP to check the pulse volume does not address the error in technique.

Option D is incorrect because confirming the accuracy of the pulse rate obtained by the UAP does not address the error in technique.

A - The injury may require medical attention, as the mother mentioned that the boy is in pain. Correct

This is the correct answer, as it reflects the nurse's assessment of the injury and the appropriate action to take. The nurse should consider the mother's report of pain as a valid indicator of the severity of the injury, and should not dismiss or minimize it.

The nurse should also observe the boy's arm and shoulder for any signs of fracture, dislocation, swelling, bruising, or deformity, and ask him to rate his pain on a scale of 0 to 10. The nurse should then decide whether to refer the boy to a physician or an emergency department for further evaluation and treatment.

B - The abrasions on the boy's leg and hand have healed.

This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The abrasions on the boy's leg and hand are not relevant to his current complaint of arm and shoulder pain, and do not indicate whether he needs medical attention or not. The nurse should focus on the boy's primary concern and not distract him with unrelated questions or comments.

C - The mother describes what she did after her child got injured.

This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The mother's description of what she did after her child got injured may provide some useful information, such as how long ago the injury occurred, what first aid measures were applied, and whether there was any improvement or worsening of symptoms. However, it does not directly answer the question of whether the injury requires medical attention or not. The nurse should listen to the mother's account, but also perform a physical examination and ask relevant questions to assess the injury.

D - The boy lacks coordination when answering the nurse's questions.

This is not the correct answer, as it does not reflect the nurse's assessment of the injury or the appropriate action to take. The boy's lack of coordination when answering the nurse's questions may indicate a possible head injury, concussion, or shock, which are serious complications that require immediate medical attention. However, it does not directly relate to his arm and shoulder pain, which is his main complaint.

The nurse should assess the boy's mental status and neurological function, but also evaluate his arm and shoulder for any signs of damage or inflammation.
