Correct Answer: B

Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading. Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.

Correct Answer: C

Rationale: To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers. Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.

Correct Answer: B

Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.

Correct Answer: C

Rationale: When assigning a floated nurse from another unit to a client in the emergency department, the goal is to choose a patient with minimal anticipated immediate complications. In this scenario, the adolescent with terminal cancer who has been on pain medications and presents with pinpoint pupils and a relaxed respiratory rate of 11 is the most stable option. These assessment findings indicate opioid toxicity, which, while serious, has the least risk of immediate complications compared to the other clients. Choice A involves a middle-aged client experiencing symptoms of possible cardiac issues due to diet pill overdose, which requires urgent intervention. Choice B presents a young adult with concerning symptoms of potential psychosis or substance withdrawal, requiring immediate attention. Choice D involves an elderly client who recently used crack, posing a high-risk situation that requires prompt evaluation and intervention. Therefore, the correct choice is the adolescent with opioid toxicity, as this client has the least immediate risk of complications among the options provided.

Correct Answer: C

Rationale: Denial is a defense mechanism where a patient rejects a reality that is too painful or difficult to accept. In the context of a terminal diagnosis, the patient may refuse to believe it in order to avoid facing the harsh truth. Regression (choice A) involves reverting to earlier, more childlike behaviors and is not applicable in this scenario. Mourning (choice B) is the process of grieving a loss, which typically occurs after acceptance of the diagnosis. Rationalization (choice D) is creating logical explanations to justify unacceptable behaviors, which is not the case when a patient denies a terminal diagnosis.
