While obtaining a health history, the nurse learns that the client is allergic to bee stings. When obtaining the client’s medication history, the nurse should determine if the client keeps which medication on hand?

Correct Answer: A

Rationale: Rationale: A: Diphenhydramine hydrochloride (Benadryl) is an antihistamine commonly used to treat allergic reactions, including those from bee stings. It can help alleviate symptoms like itching and swelling. Keeping Benadryl on hand is crucial for managing an allergic reaction promptly. Other Choices: B: Guaifenesin (Robitussin) is an expectorant used to treat coughs, not allergic reactions. C: Pseudoephedrine hydrochloride (Sudafed) is a decongestant used for nasal congestion, not allergic reactions. D: Loperamide (Imodium) is an antidiarrheal used to treat diarrhea, not allergic reactions.

Correct Answer: A

Rationale: The correct answer is A: Pregnancy. During pregnancy, the need for iron increases significantly to support the growth of the fetus and to prevent maternal anemia. Iron is essential for the production of hemoglobin and for oxygen transport in the blood. In contrast, infants require iron for rapid growth and development, making choice B partially correct. Choice C (Old age) and choice D (Male reproductive years) are incorrect as the need for iron typically decreases in old age and remains relatively stable during male reproductive years.

Correct Answer: B

Rationale: The correct answer is B: Basilic vein. It is preferred for IV therapy due to its size, accessibility, and lower risk of complications. Basilic vein is deep and stable, aiding in successful catheter insertion and reduced risk of infiltration. Jugular vein (A) is not typically used due to the high risk of complications like infection. Brachiocephalic (C) and Axillary (D) veins are less commonly used as they are smaller and more prone to complications compared to the Basilic vein. In summary, the Basilic vein is the optimal choice for initiating IV therapy due to its size, accessibility, stability, and lower risk of complications.

Correct Answer: A

Rationale: The correct answer is A: Vision changes. Tamoxifen can cause serious ocular side effects like retinopathy and corneal changes. These adverse reactions can lead to vision impairment or loss, which is crucial to report immediately to prevent permanent damage. Headache (B), hearing loss (C), and anorexia (D) are not typically associated with tamoxifen use and do not pose immediate threats to the client's health compared to vision changes. It is important for the nurse to prioritize educating the client on recognizing and reporting vision changes promptly to ensure timely intervention and prevent irreversible consequences.

Correct Answer: B

Rationale: The correct answer is B: ELISA and Western Blot. The rationale is as follows: ELISA (enzyme-linked immunosorbent assay) and Western Blot are specific tests used to confirm HIV infection by detecting antibodies or antigens related to the virus. ELISA is the initial screening test, while Western Blot is the confirmatory test. These tests are highly sensitive and specific for HIV detection. Choice A is incorrect because CD4+ cell count and thymus function are not tests used to confirm HIV infection. They are used to monitor disease progression and immune function in HIV-positive individuals. Choice C is incorrect because B-cell and T-cell count are also not tests used to confirm HIV infection. They are indicators of immune system health but not specific for HIV diagnosis. Choice D is incorrect because while CD4+ and viral load tests are used in monitoring HIV progression, ELISA is the main confirmatory test for HIV diagnosis, and viral load is not typically used for initial

Correct Answer: D

Rationale: The correct answer is D because Huntington's disease is a neurodegenerative disorder that presents with a triad of symptoms: abnormal involuntary movements (chorea), intellectual decline, and emotional disturbances. Abnormal involuntary movements are a hallmark feature, while cognitive decline and emotional disturbances are also commonly observed. Therefore, all three manifestations are typically present in individuals with Huntington's disease. Choices A, B, and C are incorrect because each of these symptoms alone does not encompass the full spectrum of clinical manifestations seen in Huntington's disease.

Correct Answer: B

Rationale: The correct answer is B: To prevent respiratory obstruction. An ice collar is used to reduce swelling and inflammation, which can help prevent the abscess from compressing the airway and causing respiratory obstruction. This is crucial in cases of peritonsillar abscess to ensure the client's airway remains patent. Choices A, C, and D do not directly address the primary concern of preventing respiratory obstruction in this context.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.

Correct Answer: A

Rationale: The correct answer is A: Filtration. Albumin is a large protein molecule that cannot pass through the semipermeable membrane of blood vessels. Therefore, the shift of body fluids associated with intravenous albumin administration occurs through the process of filtration, where fluid moves across the membrane due to a pressure difference. Osmosis (B) involves the movement of water across a semipermeable membrane, which is not the case for albumin. Diffusion (C) is the movement of molecules from an area of high concentration to low concentration, which is not how albumin moves. Active transport (D) requires energy to move substances against a concentration gradient, which is not the mechanism for albumin movement in the body.
