Introduction to Professional Nursing Quizlet Questions
Question 1 of 5
The nurse must know that the most accurate oxygen delivery system available is:
Correct Answer: A
Rationale: The correct answer is A: The venturi mask. This is the most accurate oxygen delivery system because it allows for precise oxygen concentration adjustment. The venturi mask delivers a specific oxygen concentration by mixing oxygen with room air through a system of valves and ports. This ensures a consistent and accurate oxygen delivery to the patient. Nasal cannula (B) delivers low to medium oxygen concentrations and is less accurate. Partial non-rebreather mask (C) and simple face mask (D) deliver higher oxygen concentrations but are not as precise as the venturi mask.
Question 2 of 5
While suctioning the endotracheal tube, the nurse should:
Correct Answer: B
Rationale: The correct answer is B because hyperoxygenating the client with 100% oxygen before and after suctioning helps prevent hypoxemia by providing adequate oxygenation and minimizing the risk of hypoxia during the suctioning procedure. This step is crucial in maintaining oxygen levels and preventing complications. A: Applying suction while inserting the catheter can cause trauma to the airway and increase the risk of hypoxemia. C: Using short jabbing movements can also cause trauma to the airway and is not recommended as it can lead to mucosal damage. D: Suctioning two to three times in quick succession can be harmful as it can cause hypoxemia and should be avoided to prevent complications.
Question 3 of 5
Following the death of a child, one of the parents begins to falsely accuse other members of the family of blaming the child's death on the parent. This leads to family members avoiding the mentioned parent for fear of the false accusation. The parent takes this as proof that the family truly believes the accusation. This sets up a destructive cycle of family dysfunction. Which nursing diagnosis is most appropriate for this family?
Correct Answer: D
Rationale: The correct answer is D: Dysfunctional grieving related to loss of relationships. This nursing diagnosis is most appropriate because the parent's behavior following the child's death is indicative of dysfunctional grieving, as they are falsely accusing family members and experiencing a breakdown in relationships. This behavior is a maladaptive way of coping with the loss, leading to further dysfunction within the family. A: Impaired family processes related to impaired adjustment does not fully capture the specific issue of dysfunctional grieving and loss of relationships. B: Impaired adjustment related to loneliness focuses more on the individual's emotional state rather than the family dynamics and dysfunction. C: Loneliness related to fear does not address the core issue of dysfunctional grieving and the breakdown in family relationships. In summary, the parent's behavior and the resulting family dysfunction point towards dysfunctional grieving as the primary nursing diagnosis in this case.
Question 4 of 5
The preferred site for intramuscular injection in children over 7 months and adults because the area does not contain large nerves or blood vessels is the:
Correct Answer: B
Rationale: The correct answer is B: Ventrogluteal Site. This site is preferred for intramuscular injections because it has a thick muscle mass and is located away from major nerves and blood vessels, reducing the risk of injury or complications. Steps to determine the correct answer: 1. Eliminate the Dorsogluteal Site (C) due to proximity to the sciatic nerve and superior gluteal artery, increasing the risk of nerve damage or arterial puncture. 2. Eliminate the Deltoid Site (A) which has a smaller muscle mass and is closer to the radial nerve and brachial artery, posing a higher risk of nerve injury or vascular puncture. 3. Eliminate the Vastus Lateralis Site (D) as it is often used in infants and small children due to the large muscle mass, but the ventrogluteal site is preferred in older children and adults for decreased risk of nerve and vascular injury.
Question 5 of 5
The kind of laxative that acts by causing the stool to absorb water and swell is known as:
Correct Answer: A
Rationale: The correct answer is A: Bulk forming. Bulk forming laxatives work by absorbing water in the stool, increasing its bulk and softening it for easier passage. This mechanism helps to promote regular bowel movements without causing irritation or dependency. Emollient laxatives (choice B) work by softening the stool surface. Lubricant laxatives (choice C) coat the stool and intestinal walls to ease passage. Stimulant laxatives (choice D) stimulate intestinal contractions to move stool along, but do not specifically act by causing stool to absorb water.
