The nurse is teaching a patient to wash their hands after using the bathroom as an attempt to break the chain of infection.
Between which two links in the chain of infection does this action intervene?
A. Infectious agent and reservoir.
The infectious agent is the pathogen that causes the disease, and the reservoir is where the infectious agent lives and multiplies. Hand washing does not directly intervene between these two links.
B. Mode of transmission and portal of entry.
The mode of transmission is how the infectious agent travels to other people and places, and the portal of entry is the route by which an infectious agent enters a new host. Hand washing does not directly intervene between these two links.
C. Susceptible host and infectious agent.
The susceptible host is a person who is vulnerable to the disease, and the infectious agent is the pathogen that causes the disease. Hand washing does not directly intervene between these two links.
D. Portal of exit and mode of transmission.
The portal of exit is the route by which an infectious agent escapes or leaves the reservoir, and the mode of transmission is how the infectious agent travels to other people and places. Hand washing directly intervenes between these two links by removing the infectious agent from the hands (portal of exit) and preventing its transmission to other people or surfaces.

Choice A rationale
The infectious agent is the pathogen that causes the disease, and the reservoir is where the infectious agent lives and multiplies. Hand washing does not directly intervene between these two links.
Choice B rationale
The mode of transmission is how the infectious agent travels to other people and places, and the portal of entry is the route by which an infectious agent enters a new host. Hand washing does not directly intervene between these two links.
Choice C rationale
The susceptible host is a person who is vulnerable to the disease, and the infectious agent is the pathogen that causes the disease. Hand washing does not directly intervene between these two links.
Choice D rationale
The portal of exit is the route by which an infectious agent escapes or leaves the reservoir, and the mode of transmission is how the infectious agent travels to other people and places.

A nurse is preparing to administer a heparin infusion of 25,000 units in 250 mL of normal saline at a rate of 1000 units per hour for a client diagnosed with a Deep Vein Thrombosis (DVT). The client’s initial activated partial thromboplastin time (aPTT) value is 35 seconds.
Which laboratory result would indicate that the aPTT is at a therapeutic level?
A. 30 seconds
None
B. 45 seconds
None
C. 60 seconds
None
D. 75 seconds
Step 1 is to understand the therapeutic range for aPTT when a patient is on heparin therapy. The therapeutic range for aPTT is 1.5 to 2.5 times the normal value. Given that the normal aPTT value is around 30-40 seconds, the therapeutic range would be approximately 45-100 seconds. Therefore, an aPTT value of 75 seconds falls within this therapeutic range, indicating that the heparin therapy is effective.

The nurse is providing care for a client diagnosed with post-thrombotic syndrome who has a venous stasis ulcer. Which instructions should be given prior to discharge? (Select all that apply)
A. Increase intake of proteins, take vitamin C and zinc
Proteins, vitamin C, and zinc are essential for wound healing. Proteins are the building blocks for body tissue, and zinc plays a role in protein synthesis. Vitamin C is needed for the formation of collagen, a protein used to make skin, scar tissue, and blood vessels.
B. Use care when walking to avoid bumping your limb
Care should be taken when walking to avoid bumping the limb. Any trauma to the affected limb could potentially worsen the condition or delay healing.
C. Cleanse the ulcer with soap and water
Cleaning the ulcer with soap and water may not be the best option. Soap can be irritating to the skin and may delay healing. Instead, the ulcer should be cleaned as per healthcare provider’s instructions.
D. Apply cortisone cream to decrease itching
Cortisone cream is not typically used for venous stasis ulcers. It can thin the skin and delay healing.
E. Put on compression stockings before getting out of bed
Compression stockings are often recommended for patients with post-thrombotic syndrome. They can help reduce swelling and improve blood flow, which can promote healing of the venous stasis ulcer.

A Type 1 diabetic client’s blood glucose level is 50 mg/dL at 16:30. The client is alert; however, dinner will not be served until 17:15. What should be the nurse’s initial action?
A. Have the client drink 4 oz. of orange juice
Step 1 is to understand that a blood glucose level of 50 mg/dL is considered hypoglycemic. Immediate treatment is necessary to raise the blood glucose level. Step 2 is to follow the 15-15 rule for treating hypoglycemia, which recommends consuming 15 grams of carbohydrates and then checking blood glucose levels after 15 minutes. Four ounces of orange juice contains about 15 grams of carbohydrates and can quickly raise blood glucose levels.
B. Give the client 3 tbsp.
C. of sugar dissolved in 4 oz. of grape juice to drink
D. Monitor the client closely until dinner arrives
