Which of the following would the nurse evaluate as laboratory data that support the occurrence of AIDS?

Correct Answer: D

Rationale: The nurse would evaluate 200 CD 4+ cells as laboratory data that support the occurrence of AIDS. In patients with AIDS, there is a significant decrease in the CD4+ T-lymphocyte count, typically falling below 200 cells/mm³. This low CD4+ cell count increases the risk of opportunistic infections and indicates severe immune suppression, which is characteristic of AIDS. A CD4+ count of 200 or less is an important criterion for the diagnosis of AIDS according to the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) guidelines.

Correct Answer: A

Rationale: An epinephrine (adrenaline) injection is the first-line treatment for anaphylaxis, as it helps to relax the muscles in the airway and improve breathing. This results in the client's breathing becoming easier. Epinephrine also acts to increase blood pressure, while angioedema (swelling) and a decreased level of consciousness are not expected effects of an effective epinephrine injection.

Correct Answer: C

Rationale: Oral candidiasis, also known as thrush, is a yeastlike fungal infection of the mucous membranes in the mouth. It is relatively common in newborns, as their immune systems are still developing and can be easily affected by the overgrowth of Candida fungi. Thrush can present as white patches or plaques on the tongue, gums, or inner cheeks. It is important to treat oral thrush to prevent any discomfort for the newborn and potential complications such as difficulty feeding or spreading of the infection.

Correct Answer: C

Rationale: Option C, "As you age, hormonal imbalances are the more likely cause of your disease," is the best response. Benign prostatic hyperplasia (BPH) is a common condition in aging men characterized by an enlarged prostate gland. It is predominantly influenced by hormonal changes, specifically the imbalance between levels of testosterone and estrogen as men age. This hormonal imbalance leads to the proliferation of prostatic tissue and subsequent enlargement of the prostate gland, causing symptoms such as urinary frequency, urgency, weak stream, and difficulty emptying the bladder. Chronic infection of the urinary tract (Option A) and chronic cigarette smoking (Option B) are not the primary causes of BPH. While chronic obstruction of the bladder due to a stone (Option D) can cause similar symptoms to BPH, the underlying etiology of BPH is related to hormonal changes associated with aging.

Correct Answer: D

Rationale: The neurologist tests the 4th and 6th cranial nerves together by having a patient follow his finger with his eyes. The 4th cranial nerve (trochlear nerve) innervates the superior oblique muscle, which primarily moves the eye downward and outward. The 6th cranial nerve (abducens nerve) innervates the lateral rectus muscle, which primarily moves the eye laterally. Testing these cranial nerves simultaneously by asking the patient to follow the neurologist's finger helps assess the coordination and function of both of these nerves, which are important for eye movement control.
