Question 1 of 5
A pulse is normally palpated by applying moderate pressure using:
Correct Answer: D
Rationale: The correct answer is D: The middle three fingertips. This is because using the middle three fingertips allows for more precise palpation and better detection of the pulse rhythm and rate. The thumb and index finger have larger surface areas and may not provide accurate results. The palm is too broad and may not be sensitive enough to detect subtle pulse variations. Therefore, using the middle three fingertips is the most appropriate method for palpating a pulse accurately.
Question 2 of 5
A negative peripheral pulse post cardiac catheterization indicates:
Correct Answer: A
Rationale: The correct answer is A: Clot formation on the femoral artery. A negative peripheral pulse post cardiac catheterization suggests impaired blood flow due to a clot in the femoral artery, affecting pulse palpation. Decreased oxygen on the foot (B) would not directly cause a negative pulse. Blood clots on the heart (C) would not be detected through a peripheral pulse assessment. Impending hemorrhage (D) would typically present with different signs such as hypotension or tachycardia, not a negative peripheral pulse.
Question 3 of 5
To properly perform the endotracheal insertion, the nurse:
Correct Answer: B
Rationale: Step-by-step rationale for choice B: 1. Inserting the catheter until coughing or resistance is felt ensures proper placement without causing trauma. 2. This technique helps clear secretions effectively without causing damage to the airway. 3. It allows the nurse to gauge the depth of insertion based on the patient's response. 4. Stopping at coughing or resistance prevents going too far and potentially damaging the airway. Summary: A: Turning on wall suction to 180 mmHg is incorrect as it can cause trauma to the airway. C: Withdrawing the catheter while continuously suctioning is incorrect as it can lead to hypoxia. D: Reentering the tracheostomy after suctioning the mouth is incorrect as it can introduce pathogens to the airway.
Question 4 of 5
This refers to the stiffening of the body that occurs 2–4 hours after death.
Correct Answer: B
Rationale: Rigor mortis is the correct answer as it refers to the stiffening of the body post-death, typically occurring 2-4 hours after death. This process is due to the chemical changes in the muscles, causing them to become rigid. Algor mortis refers to the cooling of the body after death. Livor mortis is the pooling of blood in the lower parts of the body post-death. Manor mortis is not a recognized term in forensic sciences.
Question 5 of 5
When giving an I.M. injection, the nurse should insert the needle into the muscle at an angle of:
Correct Answer: D
Rationale: The correct angle for an I.M. injection is 90 degrees (straight in). This angle ensures proper medication absorption and minimizes tissue damage. Inserting the needle at 15, 30, or 45 degrees can lead to suboptimal drug delivery or cause pain and discomfort. It is crucial to follow evidence-based guidelines to administer injections safely and effectively.
