HIV is easily spread through all of the listed body fluids with the exception of saliva. A person may not contract HIV through exchange of saliva during activities such as kissing or sharing eating utensils. 

HIV may be contagious just days after the host is infected. Women in heterosexual relationships may become infected more easily than men due to prolonged exposure to bodily fluids. It is however, possible for men to contract HIV from an infected woman. HIV is not frequently transmitted to health care professionals. Even for those who suffer from needle-stick injuries, transmission is unlikely.

Symptoms of acute HIV generally occur 2-4 weeks after infection. A vast array of symptoms may be present such as fever, rash, generalized fatigue, nausea, vomiting, diarrhea, and a sore throat. 

The catheter needle must be inserted bevel up at an angle between 10 to 30 degrees. The correct steps for inserting an peripheral venous catheter (PVC) are: 1) explain procedure and check identity, 2) prepare equipment at the bedside on clean surface, 3) apply appropriate personal protective equipment as needed, 4) distend veins by applying tourniquet 4-6 inches above site, 5) clean site with facility-approved cleaning solution, 6) hold skin taut to stabilize vein, 7) insert catheter bevel up at an angle between 10 and 30 degrees, 8) pierce skin and vessel to enter vein, 9) advance catheter until blood return observed, then remove tourniquet, 10) withdraw needle from catheter and advance catheter to hub, 11) secure catheter with tape or facility-approved dressing, 12) attach IV tubing and begin infusion, 13) assess for complications including infiltration or hematoma.

All of these are important nursing interventions for a post-op herniorraphy patient. The priority is to prevent increasing intraabdominal pressure. Relieving urinary retention and avoiding coughing are the most important considerations to achieve this priority, but it is most important for the nurse to remember to avoid coughing, as it is most likely to increase intraabdominal pressure. It is also important to remember because it is often promoted for other post-operative procedures, and this is one case where it is not.

Prophylactic antibiotics are not indicated for the prevention of Lyme disease. Antibiotics will be used after a tick bite when symptoms develop and an infection is suspected. The community health nurse should teach rules of prevention, including 1) knowing where Lyme disease is prevalent (New England, upper Midwest, mid-Atlantic states), 2) wearing long sleeves and long pants, covering as much skin as possible with clothing, 3) using insect repellant such as sprays over the whole body, and 4) checking for tick bites especially after exposure is anticipated, so you may receive care as quickly as possible if needed.

A patient with end-stage renal failure should be kept on a low-protein, low potassium diet. Fluid restriction is also an important part of management of patients with end-stage renal failure and patients on dialysis. 

Orange juice is very high in potassium. One 12oz glass of orange juice contains 705mg of potassium. This could easily increase blood potassium to dangerous levels. The other fruits and vegetables listed are all low-potassium foods suitable for consumption by individuals needing to follow a low potassium diet.  

BUN, or blood urea nitrogen, is a measurement of the kidney's ability to excrete urea, which is a byproduct of protein metabolism. This patient's BUN is within normal range: the reference range for BUN is .  

The correct answer is "Turning the patient multiple times per day." This is the correct answer because in the preventive stage for pressure ulcer management, there is no need to perform any invasive procedures, administer antibiotics in a patient who may be at high-risk for needing broad-spectrum antibiotics in the future (hence fostering antibiotic resistance), or consult subspecialty services (as there is no dermatological condition to be treated at the moment). The best option to prevent a pressure ulcer in a patient who is at high risk for developing a pressure ulcer is to turn the patient regularly while they are in bed, if they are bed-bound. By turning the patient, the high-pressure areas that would be at the highest risk for development of a pressure ulcer are able to have relief from pressure for a greater proportion of the day/night, and as such, can have blood flow restored while the patient is turned. By allowing for maximal blood flow to these regions, the risk of ischemia and subsequent infection and/or ulcer development is decreased. Without the actual development of an ulcer or infection, administering antibiotics, either topically, intramuscularly, or intravenously is inappropriate.
