Correct Answer: A

Rationale: The correct answer is A: Inform the physician immediately. This is because finding a lump in the breast could be a sign of breast cancer, and early detection is crucial for effective treatment. The nurse should advise the client to seek medical evaluation promptly for further assessment, such as a mammogram or biopsy. Choice B is incorrect because squeezing the nipple could potentially worsen the condition or spread cancerous cells if present. Choice C is incorrect as waiting until after the next menstrual period may delay necessary medical attention. Choice D is incorrect as using a heating pad could mask symptoms and delay proper diagnosis and treatment.

Correct Answer: D

Rationale: The correct answer is D: Cryoprecipitate. Cryoprecipitate contains high levels of clotting factors such as fibrinogen, Factor VIII, Factor XIII, and von Willebrand factor, making it the ideal choice to replace missing clotting factors in patients with bleeding disorders. Platelets (A) help with clot formation but do not contain clotting factors. Albumin (B) is a protein used for volume replacement, not clotting factor replacement. Packed RBC (C) is used to increase oxygen-carrying capacity in anemic patients, not for clotting factor replacement.

Correct Answer: C

Rationale: The correct answer is C: Hypoventilation. In chronic respiratory acidosis, the lungs cannot effectively eliminate carbon dioxide, leading to an accumulation of CO2 in the blood, causing acidosis. Hypoventilation results in decreased removal of CO2, exacerbating the acidosis. A: Hyperventilation would lead to respiratory alkalosis, not acidosis. B: Loss of acid by kidneys would result in metabolic alkalosis, not respiratory acidosis. D: Loss of base by kidneys would lead to metabolic acidosis, not respiratory acidosis. In summary, the main issue in chronic respiratory acidosis is inadequate elimination of CO2 due to hypoventilation, leading to acidosis.

Correct Answer: C

Rationale: The correct answer is C because older clients with AIDS have a faster progression of the disease due to age-related changes in the immune system, making them more vulnerable to complications. This results in a greater need for care compared to younger counterparts. Choice A is incorrect as lack of balanced diet and activity does not directly relate to the progression of AIDS. Choice B is incorrect as knowledge about disorders is not the main factor affecting the level of care needed. Choice D is incorrect as adherence to therapy is important but not the main reason older clients need more care.

Correct Answer: C

Rationale: The correct answer is C: Neck vein distention. In SIADH, there is excess release of antidiuretic hormone leading to water retention and dilutional hyponatremia, causing fluid overload. This can manifest as neck vein distention due to increased venous pressure. Tetanic contractions (A) and weight loss (B) are not typical complications of SIADH; tetany is more associated with hypocalcemia and weight loss is not a common manifestation. Polyuria (D) is actually the opposite of what is seen in SIADH, which is characterized by water retention and concentrated urine.
