Heparin 7,000 units is ordered. Heparin 5,000 units per ml is available. How many milliliters (ml) should the nurse administer?
(Do not round)
The Correct Answer is ["1.4"]
We know that 7,000 units is equivalent to 5,000 units per ml. So, we can set up the proportion:
7,000 units / 5,000 units per ml = x ml / 1 ml x = 7,000 / 5,000
x = 1.4
Therefore, the nurse should administer 1.4 milliliters (ml) of heparin.

Correct Answer is C
Explanation
Pin site care is essential to prevent infections and other complications associated with external fixation devices. The nurse should instruct the patient to clean the pin insertion sites daily with a sterile saline solution or as per healthcare provider's instructions. The patient should also observe for signs of infection, such as redness, swelling, warmth, and drainage, and report any concerns to the healthcare provider.
Assessing the skin under the foam boot twice daily is not specific to external fixation devices, and it may not be relevant to this patient's care plan. The nurse should focus on teaching the patient about external fixation device care specifically.
Taking prophylactic antibiotics before any dental work for the rest of your life is not relevant to external fixation devices or right lower leg fractures. It is a recommendation for patients with certain heart conditions who may be at risk of developing infective endocarditis during dental procedures.
Removing the external fixator for the shower is not recommended as the device should be kept dry to prevent infections. The nurse should instruct the patient to cover the device with a waterproof dressing or plastic bag during showering to protect it from getting wet.

Correct Answer is C
Explanation
Pneumonia is an infection that causes inflammation in the lungs. Auscultation refers to listening to the sounds produced by the lungs using a stethoscope. Ronchi and fine crackles are abnormal lung sounds that can be heard during auscultation in individuals with pneumonia.
These sounds are associated with the presence of fluid or mucus in the lungs, which is characteristic of pneumonia.
While other symptoms such as a sore throat, tympany noted on chest percussion, and a slightly elevated temperature (37.8 degrees Celsius) can be present in various respiratory conditions, the auscultation findings of ronchi or fine crackles specifically suggest an underlying lung infection like pneumonia.
