A nurse is assisting with the care of a client who has developed cardiogenic shock. When evaluating circulation to the client's brain, which of the following pulse sites should the nurse use?
- A. Femoral
- B. Carotid
- C. Popliteal
- D. Radial
Correct Answer: B
Rationale: The correct answer is B: Carotid. The carotid pulse site should be used when assessing circulation to the brain in a client with cardiogenic shock because it is the closest pulse site to the brain. The carotid artery supplies blood directly to the brain, making it the most accurate site to assess perfusion to this vital organ.
A: Femoral, C: Popliteal, and D: Radial are not ideal pulse sites for assessing circulation to the brain in a client with cardiogenic shock because they are further away from the brain compared to the carotid artery. Using these sites may not provide an accurate representation of cerebral perfusion in this critical situation.

A nurse is caring for a client who has a prescription for a stool guaiac test. The client asks the nurse about the purpose of the test. The nurse should respond by stating that the stool guaiac is testing for which of the following findings in the client's feces?
- A. Bacteria
- B. Parasites
- C. Blood
- D. Fat
Correct Answer: C
Rationale: The correct answer is C: Blood. A stool guaiac test is used to detect the presence of occult (hidden) blood in the feces, which may indicate gastrointestinal bleeding. This test helps in diagnosing various gastrointestinal conditions such as ulcers, polyps, or colorectal cancer. Detecting blood in the stool is crucial for early diagnosis and intervention. Choices A, B, and D are incorrect as stool guaiac test specifically looks for blood, not bacteria, parasites, or fat in the feces. Blood in the stool is a significant finding that requires further investigation, making it the appropriate response in this scenario.
A nurse is reinforcing teaching with a client who is to collect stool at home for a fecal occult blood test (FOBT). Which of the following should the nurse instruct the client to avoid for at least 3 days before the test?
- A. Whole grain cereal
- B. Magnesium hydroxide
- C. Orange juice
- D. Acetaminophen
Correct Answer: B
Rationale: The correct answer is B: Magnesium hydroxide. This is because magnesium hydroxide, commonly found in antacids and laxatives, can cause false-positive results in a fecal occult blood test (FOBT) due to its chemical reaction with the test reagents. Instructing the client to avoid magnesium hydroxide for at least 3 days before the test ensures accurate results.
Incorrect choices:
A: Whole grain cereal - Whole grain cereal does not interfere with FOBT results.
C: Orange juice - Orange juice does not impact FOBT results.
D: Acetaminophen - Acetaminophen does not affect FOBT results.
Therefore, avoiding magnesium hydroxide is crucial to obtaining reliable results in the FOBT.
While auscultating a client's heart sounds, the nurse hears turbulence between S1 and S2. The nurse should document this finding as which of the following?
- A. A systolic murmur
- B. A third heart sound (S3)
- C. An expected heart sound
- D. A fourth heart sound (S4)
Correct Answer: A
Rationale: The correct answer is A: A systolic murmur. Turbulence between S1 and S2 indicates a heart sound occurring during systole. Systolic murmurs are abnormal heart sounds heard between S1 and S2, often indicating a problem with the heart valves. S3 and S4 heart sounds occur after S2 and are associated with ventricular filling abnormalities. An expected heart sound would not exhibit turbulence. Therefore, the correct choice is A.
A provider is discharging a client with a prescription for home oxygen therapy. The nurse should reinforce which of the following instructions with the client and his family? (Select all that apply.)
- A. Cleanse the mask or collar with soapy water every other day.
- B. Make sure the straps on the mask are secure but not too tight.
- C. Check the tops of his ears regularly for skin breakdown.
- D. Post 'no smoking' warning signs at home in a prominent location.
- E. Apply petroleum jelly around and inside the nares.
Correct Answer: B,C,D
Rationale: Correct Answer: B, C, D
Rationale:
B: Making sure the straps on the mask are secure but not too tight is essential to ensure proper oxygen delivery without discomfort or skin irritation.
C: Checking the tops of the ears regularly for skin breakdown is important as the oxygen tubing can cause pressure and skin breakdown in this area.
D: Posting 'no smoking' warning signs at home in a prominent location is crucial as oxygen is highly flammable and can lead to a fire hazard if exposed to smoking or open flames.
Summary:
A: Cleansing the mask or collar with soapy water every other day is not necessary for home oxygen therapy as frequent cleaning can damage the equipment.
E: Applying petroleum jelly around and inside the nares is not recommended as it can interfere with oxygen delivery and cause respiratory issues.
