Adult Health Nursing Study Guide Answers Questions
Question 1 of 9
Which of the following immune cells is primarily responsible for coordinating and regulating immune responses by producing cytokines that direct the activities of other immune cells?
Correct Answer: A
Rationale: T helper cells (Th cells) are primarily responsible for coordinating and regulating immune responses by producing cytokines that direct the activities of other immune cells. These cytokines help in activating cytotoxic T cells, B cells, macrophages, and other cells involved in the immune response. Th cells play a crucial role in mounting an effective immune response against infections and diseases by providing the necessary signals to activate and control various immune cells. Thus, T helper cells are considered the central coordinators of the immune system.
Question 2 of 9
The BEST rationale for the conduct of the program is which of the following?
Correct Answer: D
Rationale: The BEST rationale for the conduct of the program is to deliver safe and quality nursing care to patients on intravenous therapy (IV). This directly ties the purpose of the program to the real-world outcome it seeks to achieve - providing optimal care for patients requiring intravenous therapy. Ensuring safe practice in the hospital (Option A) is important but it is not specific to the focus of the IV therapy program. Improving nursing practice in general (Option B) is a noble goal but the program should have a specific and targeted objective. Providing knowledge and skills to all nursing staff in IV Therapy (Option C) is essential, but the primary aim should be centered on improving patient care outcomes. Therefore, delivering safe and quality nursing care to patients on IV therapy aligns most closely with the core purpose of the program and should be the primary rationale.
Question 3 of 9
A patient with a history of chronic obstructive pulmonary disease (COPD) is prescribed ipratropium bromide inhaler. Which instruction should the nurse provide to the patient regarding ipratropium inhaler use?
Correct Answer: C
Rationale: The nurse should instruct the patient to hold their breath for at least 10 seconds after inhaling the medication from the ipratropium bromide inhaler. This allows the medication to reach deep into the lungs and be more effective. Holding the breath also helps reduce the risk of side effects such as throat irritation. It is essential for optimal drug delivery and therapeutic effect.
Question 4 of 9
The unit manager the planning to take her regular official business leave for the year. She has written a letter of recommendation to her Immediate supervisor for her assistant unit manager to assume her position while she is on leave. This is an example of delegation by _____.
Correct Answer: C
Rationale: Delegation by succession is the act of assigning a specific task or responsibility to someone temporarily while the usual person in charge is absent or unavailable. In this scenario, the unit manager is delegating her responsibilities to her assistant unit manager while she is on leave, indicating a temporary transfer of duties. This allows for a smooth continuity of operations within the unit during the manager's absence.
Question 5 of 9
A patient presents with chest pain that occurs during emotional stress and resolves spontaneously. An electrocardiogram (ECG) may show transient ST-segment elevation. Which cardiovascular disorder is most likely responsible for these symptoms?
Correct Answer: D
Rationale: Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or broken heart syndrome, presents with symptoms similar to acute coronary syndrome, such as chest pain and ECG changes. In Takotsubo cardiomyopathy, chest pain typically occurs during emotional stress and resolves spontaneously, similar to the scenario described in the question. The ECG may show transient ST-segment elevation. This condition is characterized by a reversible left ventricular dysfunction that can mimic a myocardial infarction. Unlike stable angina (Choice A) and unstable angina (Choice B), Takotsubo cardiomyopathy is not related to coronary artery disease. Acute myocardial infarction (Choice C) typically presents with persistent ST-segment elevation on ECG and is caused by atherosclerotic plaque rupture leading to myocardial infarction, which is not consistent with the transient ST-segment elevation seen in
Question 6 of 9
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
Correct Answer: A
Rationale: The presentation described in the question is characteristic of anterior uveitis. Anterior uveitis is inflammation of the iris and ciliary body in the eye. Patients typically present with symptoms such as redness, pain, and photophobia. Slit-lamp examination findings include ciliary injection (redness and engorgement of blood vessels in the ciliary body), corneal edema (swelling of the cornea), and a mid-dilated pupil with a fixed reaction to light due to involvement of the iris muscles. These features differentiate anterior uveitis from other conditions. Treatment of anterior uveitis may involve topical steroids and cycloplegics to reduce inflammation and alleviate symptoms.
Question 7 of 9
A woman in active labor is diagnosed with an amniotic fluid embolism. What is the priority nursing intervention?
Correct Answer: C
Rationale: An amniotic fluid embolism is a rare and life-threatening complication during labor and delivery. It occurs when amniotic fluid or fetal cells enter the maternal circulation, triggering a rapid immune response that can lead to cardiovascular collapse and respiratory failure. The priority nursing intervention for a woman in active labor diagnosed with an amniotic fluid embolism is to initiate cardiopulmonary resuscitation (CPR) to support her vital functions and circulation. Providing immediate CPR can help sustain her until further medical interventions can be implemented. Administering oxygen and preparing for a cesarean section may be necessary but should occur after CPR is initiated to stabilize the woman's condition. Inserting an indwelling urinary catheter is not the priority in this emergency situation, as maintaining adequate cardiac and respiratory function takes precedence.
Question 8 of 9
The electric fan now stops every now and then and continues to spark at intervals. The best thing to DO NEXT is to__________.
Correct Answer: A
Rationale: The best thing to do next is to turn off the fan immediately. The fact that the electric fan is stopping every now and then and sparking at intervals indicates a potential electrical issue or malfunction. This situation poses a safety hazard as it increases the risk of an electrical fire or damage to the fan. Turning off the fan immediately will help prevent any further damage or potential danger. After turning off the fan, it would be advisable to call for maintenance to inspect and repair the fan to ensure it is safe to use again.
Question 9 of 9
In collecting sputum specimen, the nurse should instruct Roy to _____.
Correct Answer: A
Rationale: In collecting a sputum specimen, the nurse should instruct Roy to breathe slowly, cough, and then expectorate into the specimen container. This ensures that the sputum sample is collected from the lower respiratory tract where it is most likely to contain pathogens or other relevant substances for analysis. By instructing Roy to breathe slowly, it helps him to take deep breaths and effectively cough to produce a good sputum sample. Additionally, asking him to expectorate directly into the specimen container helps prevent contamination from saliva or other sources, ensuring the accuracy of the specimen collected for testing.
