A patient is to receive a continuous infusion of Diltiazem at 2.5 mg hr for Atrial fibrillation, The medication is supplied 125 mg of Diltlazem in 125 mL of IV fluid. At what rate should the nurse set the IV pump? (round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["2.5"]

Ordered Dose: The doctor has prescribed Diltiazem at a rate of 2.5 mg per hour. This means the patient needs to receive 2.5 milligrams of Diltiazem every hour.

Medication Concentration: The medication is supplied as 125 mg of Diltiazem in 125 mL of fluid. This translates to a concentration of 1 mg of Diltiazem per 1 mL of solution.

Since the medication concentration is 1 mg/mL, delivering 2.5 mg of Diltiazem per hour requires infusing 2.5 mL of the solution per hour.

Therefore, the nurse should set the IV pump to deliver 2.5 mL/hr of the Diltiazem solution.

Correct Answer is C

Explanation

A) A Rhinovirus infection can cause cancer of the cervix
Rhinovirus is primarily associated with the common cold and respiratory infections, not with cervical cancer. The risk factors for cervical cancer are related to persistent infections with certain strains of the human papillomavirus (HPV), especially high-risk types like HPV-16 and HPV-18, which can lead to cervical dysplasia and, eventually, cervical cancer.

B) Eating foods high in fat and taking birth control pills are risk factors
While diet and certain medications may influence overall health, eating foods high in fat and taking birth control pills are not primary risk factors for cervical cancer. Research has shown that certain hormonal contraceptives (especially long-term use) may slightly increase the risk of cervical cancer, but the most significant and well-established risk factor is HPV infection, not fat intake or birth control use.

C) The earlier the age of sexual activity and the more partners, the greater the risk
The major risk factor for cervical cancer is persistent infection with high-risk HPV. Early initiation of sexual activity and having multiple sexual partners increase the risk of HPV infection, which is a leading cause of cervical cancer. HPV is transmitted through sexual contact, and early exposure to the virus, as well as repeated exposure to multiple partners, increases the likelihood of acquiring a high-risk strain of HPV.

D) Having yearly Pap smears will protect you from developing cancer
While Pap smears (Pap tests) are important for detecting precancerous changes (such as dysplasia) or early-stage cervical cancer, they do not prevent cancer. Pap smears can help identify abnormal cell changes that can be treated before they develop into cancer, but they do not protect against the development of cancer.

A. O- B. AB - C. A+ D. A- E. O+

Correct Answer is ["A","D"]

Explanation

A) O- (O negative):
A person with blood type A- can safely receive blood from a universal donor blood type, which is O-. This is because O- has no A, B, or Rh antigens on the surface of its red blood cells, making it compatible with any ABO blood group. The Rh negative status is also compatible, as the recipient is also Rh-negative.

B) AB- (AB negative):
A person with blood type A- cannot receive blood from someone with AB-. This is because the AB- blood type contains both A and B antigens on the surface of red blood cells, which could cause an immune reaction in a person with A- blood, whose immune system will react against the B antigen. Therefore, AB- is not compatible with A- blood.

C) A+ (A positive):
A person with A- blood cannot receive blood from an A+ donor, because the A+ blood contains the Rh positive antigen. If a person with A- blood receives Rh-positive blood, they will form antibodies against the Rh factor, leading to a hemolytic transfusion reaction. Therefore, A+ is not compatible with A- blood.

D) A- (A negative):
A person with A- blood can receive blood from another A- donor, because both share the A antigen and are Rh-negative. This is a perfect match and poses no risk of a transfusion reaction.

E) O+ (O positive):
A person with A- blood cannot receive blood from an O+ donor, because the O+ blood contains the Rh-positive antigen. This could cause an immune reaction in a person with A- blood, leading to the production of anti-Rh antibodies. Therefore, O+ is not compatible with A- blood.
