An adult has and IV line in the right forearm infusing D5 ½ NS with 20 mEq of potassium at 75 ml/h. which statement would be a correct report from the RN?

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Potassium is typically administered on a secondary line to prevent rapid infusion and potential adverse effects. 2. The primary line carries the D5 ½ NS solution without potassium, while the secondary line delivers the potassium. 3. Reporting that "potassium is on the secondary line" accurately describes the setup for this IV infusion. Summary: A: Incorrect - Incorrectly states that the potassium bag is piggybacked into the dextrose. B: Incorrect - Closing the clamp below the D5 ½ NS bag is unnecessary and does not address the potassium infusion. D: Incorrect - Fails to address the specific issue of the potassium infusion being on a secondary line.

Correct Answer: A

Rationale: The presence of redness, swelling, and induration at the wound site are indicative of infection. Redness and swelling suggest inflammation, while induration indicates tissue hardening and can be a sign of infection spreading. Infection can delay healing and lead to complications if not treated promptly. Evisceration refers to wound opening with protrusion of internal organs, not indicated by the symptoms. Dehiscence is the partial or complete separation of wound layers, not represented by the symptoms. Hemorrhage involves excessive bleeding, which is not described in the scenario. Therefore, choice A is correct as it aligns with the signs observed and is the most appropriate response for the situation.

Correct Answer: C

Rationale: The correct answer is C: Urine output increases. This indicates digoxin's effectiveness as it improves cardiac output by enhancing contraction strength. Increased urine output signifies improved kidney perfusion due to enhanced cardiac function. Option A is incorrect as decreased urine output indicates poor kidney perfusion. Option B is incorrect as digoxin aims to regulate heart rate, not necessarily make it higher than 95. Option D is incorrect as a heart rate lower than 50 could indicate digoxin toxicity.

Correct Answer: A

Rationale: The correct answer is A: The sympathetic nervous system saves fluid in response to the stress of surgery. The sympathetic nervous system is responsible for the "fight or flight" response, which includes the conservation of fluids during stressful situations. Dark amber and concentrated urine indicates dehydration, which can be a result of the sympathetic nervous system conserving fluids. B: The sympathetic nervous system does not "diereses" (increase urination) in response to stress. C: The parasympathetic nervous system is not involved in fluid conservation during stress. D: The parasympathetic nervous system does not "diereses" fluid in response to stress.

Correct Answer: C

Rationale: The correct answer is C: 5% dextrose in 0.9% NaCl. This solution is hypertonic because it has a higher osmolarity compared to the other choices. The presence of dextrose and NaCl in this solution increases its solute concentration, causing water to move out of the cells by osmosis. Normal saline (A) and 0.45% NaCl (B) are isotonic solutions, meaning they have the same osmolarity as body fluids. 0.225% NaCl (D) is a hypotonic solution with lower osmolarity than body fluids.

Correct Answer: C

Rationale: The correct answer is C: Tears and F: Breastmilk. HIV transmission has been established through breastmilk due to the presence of the virus in the milk. Tears can also transmit HIV if they contain blood from an HIV-positive individual. Saliva, sweat, and urine do not typically contain enough HIV to transmit the virus. Blood is a well-known mode of HIV transmission due to the high viral load present in blood. Therefore, choices A, B, D, and G are incorrect as they do not have sufficient levels of the virus to transmit HIV.

Correct Answer: B

Rationale: The correct answer is B: radiation therapy. Radiation therapy uses high-energy radiation to target and destroy cancer cells while minimizing damage to surrounding healthy tissues. It is a localized treatment that is effective in shrinking tumors and preventing cancer cell growth. Surgery (A) involves physically removing the tumor and surrounding tissues, while chemotherapy (C) uses drugs to kill cancer cells throughout the body. Palliative treatment (D) focuses on symptom management and improving quality of life in advanced stages of cancer. In this case, the focus is on a form of cancer therapy involving high-energy electromagnetic radiation, making radiation therapy the most appropriate choice.

Correct Answer: D

Rationale: Autoimmunity is when the immune system mistakenly attacks the body's own cells. Choice D is correct because it reflects this key feature - the inability to differentiate self from nonself. This leads to the immune system targeting healthy tissues. Choices A, B, and C are incorrect as they do not accurately describe autoimmunity. Choice A refers to endotoxins destroying B cells, which is not the definition of autoimmunity. Choice B mentions overproduction of reagin antibody, which is not related to autoimmunity. Choice C is incorrect as autoimmunity does not involve depression of the immune response but rather an inappropriate immune response.

Correct Answer: D

Rationale: The correct answer is D, suggesting the use of glasses or contact lenses. This is because as older clients experience lens changes associated with aging, they may develop presbyopia or other vision issues that can be corrected with corrective lenses. Glasses or contact lenses can help improve their vision and quality of life. A, offering teaching aids with large-sized letters, may be helpful for clients with visual impairments but may not directly address the specific lens changes associated with aging. B, suggesting reduced visual activity, is not beneficial as it may further limit the client's engagement in daily activities and social interactions. C, suggesting the use of eye drops for comfort, may provide temporary relief for dry eyes but does not address the underlying lens changes affecting vision.
