Question 1 of 5
Which type of Leukocyte is involved with allergic responses and the destruction of parasitic worms?
Correct Answer: C
Rationale: Eosinophils are the correct answer. Eosinophils are specialized white blood cells that play a crucial role in allergic responses and combating parasitic infections. They release substances to destroy parasites and modulate allergic reactions. Neutrophils (
Choice
A) are mainly involved in fighting bacterial infections. Lymphocytes (
Choice
B) play a key role in the immune response, including antibody production, but are not primarily responsible for combating parasites or allergic responses. Monocytes (
Choice
D) are involved in immune defense, differentiating into macrophages or dendritic cells, but they are not mainly associated with allergic responses or parasitic worm destruction.
Question 2 of 5
A client with skin grafts covering full-thickness burns on both arms and legs is scheduled for a dressing change. The client is nervous and requests that the dressing change be skipped this time. What action is most important for the nurse to take?
Correct Answer: A
Rationale: In this situation, the most important action for the nurse to take is to explain the importance of regular dressing changes to the client. By doing so, the nurse can help the client understand the necessity for wound healing and infection prevention. Administering anti-anxiety medication (
Choice
B) may not address the root cause of the client's anxiety, which is the lack of understanding. Proceeding with the scheduled dressing change (
Choice
C) without addressing the client's concerns can worsen their anxiety and decrease trust. Encouraging the client to express any anxieties (
Choice
D) is important but not as crucial as ensuring the client comprehends the rationale behind the dressing change.
Question 3 of 5
An angry client screams at the emergency department triage nurse, "I've been waiting here for two hours! You and the staff are incompetent". What is the best response for the nurse to make?
Correct Answer: D
Rationale:
Correct
Answer: The best response for the nurse is to choose option D, 'I understand you are frustrated with the wait time.' This response demonstrates empathy and validates the client's feelings, helping to defuse the situation.
Choice A is not the best response as it does not directly address the client's emotions or concerns.
Choice B is inappropriate as it gives preferential treatment based on the client's behavior.
Choice C, while true, does not acknowledge the client's frustration or offer empathy.
Question 4 of 5
When caring for a laboring client whose contractions are occurring every 2 to 3 minutes, the nurse should document that the pump is infusing how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number. Click on each chart tab for additional information. Please be sure to scroll to the bottom right corner of each tab to view all information contained in the client's medical record.)
Correct Answer: A
Rationale: By calculating the infusion rate based on the given chart information, the correct value is 42 ml/hr. This rate ensures proper fluid administration to the laboring client.
Choices B (38), C (48), and D (50) are incorrect as they do not align with the calculated infusion rate needed for the client's condition, as per the chart data provided.
Question 5 of 5
To manage the client's constipation, which suggestions should the nurse provide? (Select all that apply)
Correct Answer: C
Rationale: The correct answer is C. Increasing fluid intake is essential for managing constipation. Adequate hydration helps soften stool and promotes bowel movements.
Choices A and B are incorrect as decreasing laxative use without medical advice and suggesting specific foods like oatmeal with stewed prunes may not be suitable for every individual with constipation.
Choice D is also incorrect as while seeking help with meal preparation can indirectly aid in managing constipation, the immediate need is to increase fluid intake.
