Which technique will provide the most accurate measurement of the patient’s core temperature?

Choice A reason: This is an incorrect choice because perceived constipation related to expectation of daily bowel movements is not an appropriate nursing diagnosis for this patient. Perceived constipation is a subjective problem that occurs when the patient's bowel elimination pattern does not meet their personal expectations. The patient may not have any objective signs of constipation, such as hard stools, straining, or abdominal discomfort. This diagnosis is not applicable to this patient, who has objective signs of constipation and a clear cause of the problem.

Choice B reason: This is an incorrect choice because impaired bowel elimination related to abdominal muscle weakness is not an appropriate nursing diagnosis for this patient. Impaired bowel elimination is a problem that occurs when the patient has difficulty in passing stools or has a change in bowel habits. Abdominal muscle weakness is a possible factor that can affect bowel function, but it is not the cause of the problem for this patient. This diagnosis is not applicable to this patient, who has a normal muscle strength and a clear cause of the problem.

Choice C reason: This is an incorrect choice because risk for constipation related to irregular defecation habits is not an appropriate nursing diagnosis for this patient. Risk for constipation is a potential problem that occurs when the patient is vulnerable to developing constipation due to various factors. Irregular defecation habits are a possible factor that can increase the risk of constipation, but they are not the cause of the problem for this patient. This diagnosis is not applicable to this patient, who already has constipation and a clear cause of the problem.

Choice D reason: This is the correct choice because constipation related to side effects of pain medication is an appropriate nursing diagnosis for this patient. Constipation is a problem that occurs when the patient has infrequent, difficult, or incomplete bowel movements. Pain medication, especially opioids, are a common cause of constipation, as they can slow down the gastrointestinal motility and reduce the stool volume and water content. This diagnosis is applicable to this patient, who has objective signs of constipation and a clear cause of the problem..

Choice A reason: This is incorrect. Documenting the finding in the patient’s medical record is an important step, but not the most appropriate first action of the nurse. The nurse should first confirm the irregularity by counting the apical pulse.

Choice B reason: This is incorrect. Assessing the brachial pulse for a pulse deficit is a useful technique, but not the most appropriate first action of the nurse. A pulse deficit is the difference between the apical and radial pulse rates. The nurse should first count the apical pulse before comparing it with the radial pulse.

Choice C reason: This is incorrect. Notifying the health care provider immediately is a necessary step, but not the most appropriate first action of the nurse. The nurse should first gather more information by counting the apical pulse and determining the type and severity of the irregularity.

Choice D reason: This is correct. Counting the patient’s apical pulse for one full minute is the most appropriate first action of the nurse. The apical pulse is the most accurate way to measure the heart rate and rhythm. The nurse should listen to the heart sounds at the apex of the heart, which is located at the fifth intercostal space, left midclavicular line. The nurse should count the number of beats and note any irregularities, such as skipped, extra, or uneven beats..
