1. What is the correct procedure for performing an ophthalmoscopic examination on a client's right retina?

• A. Instruct the client to focus on a distant object behind the examiner and not move their eyes during the exam.
• B. Set the ophthalmoscope on the plus 2 to 3 lens and hold it in front of the examiner's right eye.
• C. From a distance of 12 to 15 inches and slightly to the side, shine the light into the client's pupil.
• D. For optimal visualization, keep the ophthalmoscope at least 3 inches from the client's eye.

Correct answer: C

Rationale: During an ophthalmoscopic examination, the client should focus on a distant object behind the examiner to dilate the pupil, and the examiner should stand at a distance of 12-15 inches away and slightly to the side. This angle allows for better visualization of the retina. Holding the ophthalmoscope firmly against the examiner's face and shining the light into the client's pupil helps examine the retina effectively. Choice A is incorrect because the client should look at a distant object, not the examiner's nose. Choice B is incorrect as the ophthalmoscope should be directed towards the client's eye, not the examiner's eye. Choice D is incorrect because keeping the ophthalmoscope at least 3 inches away may not provide an optimal view of the retina.

2. A nurse is preparing for intershift report when a nurse’s aide pulls an emergency call light in a client’s room. Upon answering the light, the nurse finds a client who returned from surgery earlier in the day experiencing tachycardia and tachypnea. The client’s blood pressure is 88/60 mm Hg. Which action should the nurse take first?

• A. Calling the physician
• B. Checking the hourly urine output
• C. Checking the IV site for infiltration
• D. Placing the client in a modified Trendelenburg position

Correct answer: D

Rationale: The client is exhibiting signs of shock, indicated by tachycardia, tachypnea, and hypotension. Placing the client in a modified Trendelenburg position is the initial action to improve venous return, cardiac output, and subsequently increase blood pressure. This position helps redistribute blood flow to vital organs. Calling the physician should follow once immediate intervention has been initiated. Checking the hourly urine output and IV site are important assessments but are secondary to addressing the client's hemodynamic instability and potential for shock.

3. A client with type 1 diabetes mellitus who jogs daily is being taught by a nurse about the preferred sites for insulin absorption. What is the most appropriate site for this client?

• A. Arms
• B. Legs
• C. Abdomen
• D. Iliac crest

Correct answer: C

Rationale: The abdomen is the most appropriate site for insulin absorption in a client who jogs. When a client is involved in physical activity like jogging, the abdomen is preferred as it provides more consistent absorption compared to the arms or legs, which can have altered absorption rates due to increased blood flow during exercise. The iliac crest is not a common site for insulin injections and may not provide optimal absorption rates compared to the abdomen.

4. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?

• A. Muscle cramps.
• B. Hypertension.
• C. Bradycardia.
• D. Tachycardia.

Correct answer: D

Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.

5. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.
