1. The most accurate reading for a temperature is done:

A. Orally
B. Aurally through a clean canal
C. Rectally
D. Axially

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.

2. During change-of-shift report, the nurse learns about the following four patients. Which patient requires assessment first?

A. 40-year-old with chronic pancreatitis who has gnawing abdominal pain
B. 58-year-old who has compensated cirrhosis and is complaining of anorexia
C. 55-year-old with cirrhosis and ascites who has an oral temperature of 102�F (38.8�C)
D. 36-year-old recovering from a laparoscopic cholecystectomy who has severe shoulder pain

Correct answer: C

Rationale: When prioritizing patient assessments, the nurse should address the patient with cirrhosis and ascites who has an elevated oral temperature of 102�F (38.8�C) first. This presentation suggests a potential infection, which is critical to address promptly in a patient with liver disease. An infection in a patient with cirrhosis can quickly progress to severe complications. The other options, such as chronic pancreatitis with abdominal pain, compensated cirrhosis with anorexia, and post-laparoscopic cholecystectomy with shoulder pain, do not indicate an immediate life-threatening situation requiring urgent assessment compared to a possible infection in a patient with cirrhosis and ascites.

3. A client is taking a walk down the hallway when she suddenly realizes that she needs to use the restroom. Although she tries to make it to the bathroom on time, she is incontinent of urine before reaching the toilet. What type of incontinence does this situation represent?

A. Relex incontinence
B. Urge incontinence
C. Total incontinence
D. Functional incontinence

Correct answer: D

Rationale: Functional incontinence occurs when a client develops an urge to void but may not be able to reach the toilet in time. In this scenario, the client had the urge to use the restroom but was unable to make it in time, leading to incontinence. Functional incontinence may be related to conditions that cause the client to forget bladder sensation until the last minute, such as cognitive changes, or the client may have mobility problems that prevent her from reaching the bathroom in time. Choice A, Reflex incontinence, is incorrect as reflex incontinence is characterized by the involuntary loss of urine due to hyperreflexia of the detrusor muscle. Choice B, Urge incontinence, is not the correct answer as urge incontinence is the involuntary loss of urine associated with a strong desire to void. Choice C, Total incontinence, is also incorrect as it refers to the continuous and unpredictable loss of urine, not specifically related to the inability to reach the toilet in time.

4. The nurse is preparing to perform a physical assessment. The correct action by the nurse is reflected by which statement?

A. Performs the examination from both sides of the bed.
B. Examines tender or painful areas last to help relieve the patient's anxiety.
C. Follows a flexible examination sequence, considering the patient's age and condition.
D. Organizes the assessment to ensure that the patient does not change positions too often.

Correct answer: D

Rationale: The nurse should organize the assessment to minimize the patient's need to change positions frequently, ensuring efficiency and comfort. It is essential to perform the examination from both sides of the bed to facilitate a comprehensive assessment. Examining tender or painful areas last can help reduce patient discomfort and anxiety. The examination sequence should be flexible, taking into account the patient's age, condition, and specific needs. This approach allows for a tailored and patient-centered assessment, optimizing the quality of care provided.

5. Where is the Loop of Henle located in the body?

A. Liver
B. Kidney
C. Heart
D. Ear

Correct answer: B

Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.
