An adult client comes to the clinic and reports concern over a lump that, "Just popped up on my neck about a week ago." While performing an examination of the lump, the nurse palpates a large, nontender, hardened left subclavian lymph node. There is no overlying tissue inflammation. Which of these findings suggest?
Lymphangitis.
Malignancy.
Viral Infection.
Bacterial Infection.
The Correct Answer is B
A. Lymphangitis is characterized by inflammation of the lymphatic vessels and is often associated with red streaks and tenderness. The absence of inflammation and tenderness suggests a different etiology.
B. Malignancy is suggested by the presence of a large, nontender, hardened lymph node. These characteristics are commonly associated with metastatic spread of cancer to the lymph nodes. Further diagnostic testing, such as biopsy, would be warranted to confirm malignancy.
C. Viral infection may cause lymphadenopathy, but typically, the lymph nodes are tender and may be enlarged but not necessarily hardened. The absence of tenderness and the hardened consistency of the lymph node suggest a different etiology.
D. Bacterial infection can cause lymphadenopathy, which may be tender and enlarged, but the nontender, hardened nature of the lymph node in this case is more indicative of malignancy
rather than a bacterial infection.

Correct Answer is D
Explanation
A. Verify the prothrombin time (PT).
While it is important to verify coagulation status in patients with atrial fibrillation to ensure they are not at high risk for bleeding, this is not the most critical step immediately prior to
cardioversion. The PT is more relevant if anticoagulation therapy is being managed.
B. Administer prescribed sedative.
Administering a sedative is important for patient comfort during the procedure, but it is not the most critical step that directly affects the success and safety of the cardioversion itself.
C. Select a monitor lead with a tall R wave.
Selecting a monitor lead with a tall R wave helps in accurately synchronizing the cardioversion shock with the R wave, but this is secondary to activating the synchronization mode which is critical to avoid delivering a shock during the vulnerable period of the cardiac cycle.
D. Activate the synchronization mode.
This is the correct answer. The most important action before deploying the current for cardioversion is to ensure the defibrillator is in synchronization mode. Synchronization ensures that the electrical shock is delivered at the correct time during the cardiac cycle, specifically on the R wave of the QRS complex, to avoid inducing ventricular fibrillation. This is crucial for
patient safety.
Correct Answer is ["1.8"]
Explanation
Steps to solve:
- Convert the client's weight from pounds to kilograms:
- Weight (kg) = Weight (pounds) / 2.20462
- Weight (kg) = 132 pounds / 2.20462 ≈ 59.87 kg (round to nearest tenth for medication calculation)
- Calculate the total dantrolene dosage based on the prescribed dosage per kilogram:
-
- Dosage (mg) = Weight (kg) x Dosage per kg
-
- Dosage (mg) = 59.87 kg x 1.5 mg/kg
-
- Dosage (mg) ≈ 89.8 (round to nearest tenth)
- Determine the concentration of dantrolene after reconstitution:
- Concentration = 50 mg/mL (given on the vial label)
- Calculate the volume of the solution to administer:
-
- Volume (mL) = Dosage (mg) / Concentration (mg/mL)
-
- Volume (mL) = 89.8 mg / 50 mg/mL
-
- Volume (mL) ≈ 1.79 mL (round to one decimal place)= 1.8mL
