For a rectal examination, the patient can be directed to assume which of the following positions?

Correct Answer: B

Rationale: For a rectal examination, patient positioning is crucial for optimal access, visualization, and comfort. The **Sims position (B) is correct** because it allows the patient to lie on their left side with the right knee and hip flexed toward the abdomen while the left arm rests behind the body. This position provides excellent exposure of the anorectal area, facilitates relaxation of the anal sphincter, and is comfortable for the patient while allowing the clinician easy access for examination or procedures. It is widely recognized as the standard for rectal exams due to its practicality and effectiveness. **Choice A (Genupectoral)** is incorrect because, while it does provide exposure of the anal region, it is not the standard for routine rectal exams. The genupectoral (or knee-chest) position involves the patient resting on their knees and chest, which can be uncomfortable, embarrassing, or physically challenging for many patients, particularly the elderly or those with mobility issues. This position is more commonly used for procedures like sigmoidoscopy rather than a basic rectal examination. **Choice C (Horizontal recumbent)** is incorrect because lying flat on the back does not provide adequate exposure of the rectum for examination. The supine position makes it difficult to access the anal area properly and can lead to poor visualization and an uncomfortable experience for both patient and clinician. Some modified supine positions (e.g., lithotomy) may be used in certain clinical settings, but the standard horizontal recumbent position is impractical for a rectal exam. **Choice D (All of the above)** is incorrect because while multiple positions can technically be used, they are not equally appropriate. Only the Sims position is the universally recommended standard for routine rectal exams due to its balance of accessibility, patient comfort, and clinical effectiveness. Including other positions as equally valid would misrepresent best clinical practices. Thus, the correct answer is **B (Sims)**, as it is the most practical, comfortable, and effective position for a rectal examination, whereas the other options either present disadvantages or are not standard practice. The rationale emphasizes anatomical accessibility, patient comfort, and clinical appropriateness in determining the best choice.

Correct Answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

Correct Answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

Correct Answer: D

Rationale: When assessing respirations, it is essential to evaluate the rate at which breaths are taken, the rhythm of breathing patterns, and the symmetry of chest expansion. Each of these parameters provides valuable information about a person's respiratory status. Therefore, it is important to assess all of the listed parameters to have a comprehensive understanding of the individual's respiratory function.

Correct Answer: D

Rationale: The axillary temperature of 99.6°F (37.6°C) is mildly elevated, as normal axillary temperature typically ranges from 97.6°F (36.4°C) to 98.1°F (36.7°C). While this alone may not always warrant immediate reporting, it becomes significant when paired with other abnormal findings. The respiratory rate of 30 breaths per minute is notably high, as the normal range for adults is 12–20 breaths per minute. Tachypnea (elevated respiratory rate) often indicates respiratory distress, infection, or metabolic disturbances, making it a critical finding that must be reported. The pulse rate of 88 falls within the normal range (60–100 beats per minute) and does not raise immediate concern. **Why D is correct:** Both the elevated temperature and the significantly increased respiratory rate are abnormal and clinically significant. Together, they suggest a potential underlying condition such as infection, sepsis, or respiratory compromise, necessitating prompt evaluation. Reporting these findings ensures timely intervention. **Why A is incorrect:** While the respiratory rate is abnormal and should be reported, ignoring the elevated temperature overlooks a key piece of clinical data. Fever can indicate infection or inflammation, and when combined with tachypnea, it strengthens the case for further assessment. **Why B is incorrect:** Reporting the temperature alone neglects the more urgent finding of tachypnea. A mildly elevated temperature without other symptoms may not always require immediate action, but the respiratory rate of 30 is a red flag that demands attention. **Why C is incorrect:** The pulse rate is normal and does not require reporting. While the temperature is slightly elevated, it is less concerning without additional abnormal findings. Pairing it with the normal pulse rate does not provide enough clinical significance to prioritize reporting over the respiratory rate. The combination of temperature and respiratory rate provides a clearer picture of potential physiological stress or pathology, making D the most appropriate choice for reporting. Ignoring either of these findings could delay diagnosis and treatment of a potentially serious condition.
