Nursing Elites

1. 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.

2. Which type of shock is related to low blood volume?

• A. Psychogenic
• B. Cardiogenic
• C. Anaphylactic
• D. Hemorrhagic

Correct answer: D

Rationale: Hemorrhagic shock, also known as hypovolemic shock, is directly related to low blood volume due to significant blood loss. In hemorrhagic shock, the body's circulating blood volume is reduced, leading to inadequate perfusion of tissues and organs. Psychogenic shock is caused by emotional distress, not blood volume changes. Cardiogenic shock results from heart failure, not low blood volume. Anaphylactic shock is due to a severe allergic reaction, not a reduction in blood volume.

3. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

• A. "The numbers are within the normal range and are nothing to worry about."?
• B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
• C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
• D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.

4. When a nurse's hand comes in contact with a client's blood after providing wound care, what is the next action the nurse should take?

• A. Use an alcohol-based hand sanitizer to disinfect the hands
• B. Wash hands with soap and water using appropriate technique
• C. Notify the appropriate personnel about the exposure to client's blood
• D. Sample some of the client's blood to determine the presence of diseases

Correct answer: B

Rationale: When a nurse's hand comes in contact with a client's blood, it is important to follow appropriate infection control measures. Using an alcohol-based hand sanitizer is not sufficient in this scenario as the blood is a visible contaminant. The best practice is to wash hands with soap and water using appropriate technique to ensure thorough cleansing and removal of any potential pathogens. Notifying the appropriate personnel about the exposure is important for documentation and further evaluation, but immediate hand hygiene is crucial. Sampling the client's blood for disease determination is not within the nurse's scope of practice and is unnecessary in this situation.

5. A 51-year-old woman had an incisional cholecystectomy 6 hours ago. The nurse will place the highest priority on assisting the patient to

• A. choose low-fat foods from the menu
• B. perform leg exercises hourly while awake
• C. ambulate the evening of the operative day
• D. turn, cough, and deep breathe every 2 hours

Correct answer: D

Rationale: Postoperative nursing care after a cholecystectomy focuses on preventing respiratory complications due to the surgical incision being high in the abdomen, which impairs coughing and deep breathing. Turning, coughing, and deep breathing every 2 hours help prevent respiratory complications, such as pneumonia. While choices A, B, and C are also important aspects of postoperative care, they are not as high a priority as ensuring proper ventilation and respiratory function in the immediate postoperative period.
