1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. What is the best position for examining the rectum?

• A. Prone
• B. Sim's
• C. Knee-chest
• D. Lithotomy

Correct answer: C

Rationale: The knee-chest position is the most optimal position for examining the rectum. In this position, the patient kneels on the examination table with their chest resting on it, creating a straight line from the head to the lower back. This position allows for easier access and visualization of the rectal area, making it the preferred choice for rectal examinations. Prone position (choice A) is lying face down and is not ideal for rectal exams as it does not provide good access. Sim's position (choice B) is lying on the left side with the right knee and thigh flexed, also not ideal for rectal exams. Lithotomy position (choice D) is lying on the back with legs flexed and feet in stirrups, primarily used for gynecological exams and surgery, not for rectal examinations.

3. If a patient's blood pressure is 150/96, what is his pulse pressure?

• A. 54
• B. 96
• C. 150
• D. 246

Correct answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

4. Which term is best described as a systematic, rational method of planning and providing nursing care for individuals, families, groups, and communities?

• A. Assessment
• B. Nursing Process
• C. Diagnosis
• D. Implementation

Correct answer: B

Rationale: The correct answer is B: Nursing Process. The nursing process is a systematic, rational method that guides nurses in planning and delivering patient care. It involves a series of steps including assessment, diagnosis, planning, implementation, and evaluation. By utilizing the nursing process, nurses can provide individualized care tailored to the specific needs of patients, families, groups, and communities. Choice A, Assessment, is a step within the nursing process but does not encompass the entire process itself. Choice C, Diagnosis, is another step within the nursing process and focuses on identifying the patient's health problems. Choice D, Implementation, is also a step in the nursing process where the care plan is put into action, but it does not solely describe the entire systematic and rational method of planning and providing nursing care.

5. When assessing a client with sinusitis, which technique should the nurse use to identify manifestations of this disorder?

• A. Percussion of the frontal sinuses
• B. Auscultation of the trachea
• C. Inspection of the nasal mucosa
• D. Palpation of the orbital areas

Correct answer: D

Rationale: Sinusitis is an inflammation of the sinus cavities, which can cause tenderness and pain around the eyes (orbital areas). Palpation of the orbital areas can help identify tenderness and swelling associated with sinusitis. Auscultation of the trachea and percussion of the frontal sinuses are not relevant assessment techniques for sinusitis. Inspection of the nasal mucosa may reveal signs of inflammation, but palpation of the orbital areas is a more direct method to assess for tenderness and swelling in this specific condition.
