The knows that a positive diagnosis for HIV infection is made based on; a.A history of high-risk sexual behaviors
- A. Positive ELISA and Western blot tests
- B. Evidence of extreme weight loss and high fever
- C. Identification of an associated opportunistic infection
Correct Answer: A
Rationale: The definitive diagnosis of HIV infection is made based on the detection of specific antibodies in the blood. The most commonly used tests for this purpose are ELISA (Enzyme-Linked Immunosorbent Assay) and Western blot. A positive result on both tests confirms the presence of HIV antibodies in the blood, indicating an active HIV infection. High-risk sexual behaviors, extreme weight loss, and opportunistic infections may raise suspicion for HIV infection, but a positive diagnosis is confirmed through specific laboratory tests like ELISA and Western blot.

A patient has cloudy penile discharge. For which additional symptoms of urethritis should the nurse assess?
- A. Throat or rectal infection
- B. Chancres or vesicles on the genitals
- C. Painful and frequent urination
- D. Oliguria and flank pain
Correct Answer: C
Rationale: Cloudy penile discharge is a common symptom of urethritis, which is inflammation of the urethra usually caused by an infection, such as a sexually transmitted infection (STI) like gonorrhea or chlamydia. Painful and frequent urination are also classic symptoms of urethritis. Painful urination, or dysuria, may occur due to the irritation and inflammation of the urethra. Frequency of urination can be a result of the body's response to the infection or inflammation. Therefore, assessing for these additional symptoms helps in confirming the diagnosis of urethritis and determining the appropriate treatment for the patient.
The nurse is caring for a client in the emergency room diagnosed with Bell's palsy. The client has been taking acetaminophen (Tylenol), and acetaminophen overdose is suspected. The nurse anticipates that the antidote to be prescribed is:
- A. Pentostatin (Nipent)
- B. Fludarabine (Fludara)
- C. Auranofin (Ridaura)
- D. Acetylcysteine Mucomyst)
Correct Answer: D
Rationale: Acetylcysteine (Mucomyst) is the antidote for acetaminophen (Tylenol) overdose. If an overdose of acetaminincophen is suspected, acetylcysteine should be administered within 8-10 hours of ingestion to prevent liver damage and failure. Pentostatin, Fludarabine, and Auranofin are not antidotes for acetaminophen overdose and are used for other medical conditions.
The single parent of a 3-year-old child who has just been diagnosed with chickenpox tells the nurse that she cannot afford to stay home with the child and miss work. The parent asks the nurse if some medication will shorten the course of the illness. Which is the most appropriate nursing intervention?
- A. Reassure the parent that it is not necessary to stay home with the child.
- B. Explain that no medication will shorten the course of the illness.
- C. Explain the advantages of the medication acyclovir (Zovirax) to treat chickenpox.
- D. Explain the advantages of the medication VCZ immune globulin (VariZIG) to treat chickenpox.
Correct Answer: B
Rationale: The most appropriate nursing intervention in this scenario is to explain to the parent that no medication will shorten the course of chickenpox. Chickenpox is a viral illness caused by the varicella-zoster virus, and there is no specific treatment to shorten its duration. Antiviral medications like acyclovir are typically reserved for severe cases or for individuals with compromised immune systems. VCZ immune globulin (VariZIG) is used for post-exposure prophylaxis in susceptible individuals who have been exposed to chickenpox and are at high risk for severe disease.
A client is admitted to the ICU, which laboratory result must be reported immediately to the physician?
- A. Hematocrit 48%
- B. paCO2 38 mm Hg
- C. platelets 18,000
- D. WBC count 8000
Correct Answer: C
Rationale: A platelet count of 18,000 is significantly low, indicating a condition known as thrombocytopenia, which can lead to a risk of bleeding. In a critical care setting like the ICU, low platelet counts need to be addressed urgently to prevent serious complications such as hemorrhage. This result must be reported immediately to the physician so that appropriate interventions, such as transfusion of platelets, can be initiated promptly to manage the patient's condition effectively. Hematocrit, paCO2, and WBC count may also be important parameters to monitor in an ICU patient, but the critically low platelet count poses the most immediate threat to the patient's well-being and requires urgent attention.
. A client with a suspected left sided heart failure is scheduled to undergo a multigated acquisition scan. Which of the following actions is required before undergoing the test?
- A. Diuretics are administered
- B. Client should avoid fluid intake 6 hours
- C. Client is medicated to relieve cough before the test
- D. Client is administered analgesics
Correct Answer: C
Rationale: Before undergoing a multigated acquisition scan, a client with suspected left sided heart failure should be medicated to relieve cough. Coughing can disrupt the accuracy of the scan results by affecting the heart's movement and leading to motion artifacts. Therefore, it is essential to address any coughing issues before the test to ensure reliable and accurate imaging of the heart's function. The other options, such as administering diuretics, avoiding fluid intake, and administering analgesics, are not directly related to optimizing the imaging quality of the multigated acquisition scan for a client with suspected left sided heart failure.
