Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?
- A. Increasing heart rate above normal for the patient's age.
- B. Absent peripheral pulses
- C. Decreasing level of consciousness
- D. Increasing blood pressure
Correct Answer: D
Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.

Which of the following is TRUE about shock?
- A. A patient with severe shock does not always have an abnormally low blood pressure.
- B. Confusion and deteriorating mentation are indicative of hypotensive shock.
- C. Patients with compensated shock may not be able to maintain a normal blood pressure.
- D. A normal blood pressure does not imply that the patient is stable.
Correct Answer: B
Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.
A mother brings her child to the well-child clinic and expresses concern to the nurse because the child has been playing with another child diagnosed with hepatitis. The nurse prepares to perform an assessment on the child, knowing that which finding would be of least concern for hepatitis?
- A. Jaundice
- B. Hepatomegaly
- C. Dark-colored, frothy urine
- D. Left upper abdominal quadrant pain
Correct Answer: D
Rationale: Assessment findings in a child with hepatitis typically include right upper quadrant tenderness and hepatomegaly. The child may also present with pale, clay-colored stools and dark, frothy urine. Jaundice, which can be observed in the sclerae, nail beds, and mucous membranes, is a common sign of hepatitis. Left upper abdominal quadrant pain is not a typical finding associated with hepatitis; therefore, it would be of least concern in this scenario. The other options are more commonly associated with hepatitis and are important signs to monitor for in a child with possible exposure to the virus.
After repair of an inguinal hernia, the infant is being cared for. Which assessment finding indicates that the surgical repair was effective?
- A. A clean, dry incision
- B. Abdominal distension
- C. An adequate flow of urine
- D. Absence of inguinal swelling with crying
Correct Answer: D
Rationale: The absence of inguinal swelling when the infant cries or strains indicates that the surgical repair of the inguinal hernia was effective. Inguinal swelling typically occurs with crying or straining in cases of this condition. A clean, dry incision signifies the absence of wound infection post-surgery but does not directly indicate the effectiveness of the hernia repair. Abdominal distension suggests a gastrointestinal issue unrelated to the hernia repair. An adequate flow of urine is not specific to evaluating the success of inguinal hernia repair.
The physician has decided to perform a thoracentesis based on Mr. R's assessment. Which of the following actions from the nurse is most appropriate?
- A. Instruct the client not to talk during the procedure
- B. Assist the client to sit upright or slightly lean forward
- C. Insert a 20-gauge needle just above the 4th intercostal space
- D. Connect the needle to suction to remove fluid that has collected in the pleural space
Correct Answer: A
Rationale: The correct answer is to instruct the client not to talk during the procedure. This is important to prevent air from being drawn into the pleural space during the thoracentesis. Choice B is incorrect because the client should be sitting upright or slightly leaning forward during the procedure to facilitate access to the pleural space. Choice C is incorrect as the nurse should not perform the thoracentesis procedure, which involves inserting a needle into the pleural space - this is the physician's responsibility. Choice D is incorrect as connecting the needle to suction to remove fluid is not the appropriate procedure for a thoracentesis. Thoracentesis is typically done to remove fluid or air for diagnostic or therapeutic purposes, not to connect to suction to remove fluid that has collected in the pleural space.
A child is diagnosed with a Greenstick Fracture. Which of the following most accurately describes the broken bone?
- A. compound fracture of the fibula
- B. a partial break in a long bone
- C. fracture of the growth plate of the ulna near the wrist
- D. Colles fracture of the tibia
Correct Answer: B
Rationale: A Greenstick Fracture is commonly found in children due to their bones being more flexible. This type of fracture occurs when a bone bends and partially breaks, resembling what happens when a green stick from a tree is bent in half. Therefore, the most accurate description of a Greenstick Fracture is 'a partial break in a long bone.' Choice A, 'compound fracture of the fibula,' is incorrect as a Greenstick Fracture is not a compound fracture. Choice C, 'fracture of the growth plate of the ulna near the wrist,' is incorrect as it describes a different type of fracture. Choice D, 'Colles fracture of the tibia,' is incorrect as it refers to a specific type of fracture in a different bone.
