Which painful, tender, pea-sized nodules may appear on the pads of the fingers or toes in bacterial endocarditis?

Correct Answer: A

Rationale: Osler nodes are painful, tender, pea-sized nodules that can appear on the pads of the fingers or toes and are associated with bacterial endocarditis. These nodules result from immune-complex deposition in the small blood vessels of the skin. They are not to be confused with Janeway lesions, which are painless, non-tender macules found on the palms and soles in infective endocarditis. Subcutaneous nodules are seen in conditions like rheumatic fever, while Aschoff nodes are characteristic of rheumatic fever involving the heart.

Correct Answer: B

Rationale: For a client with hyperosmolar hyperglycemic nonketotic syndrome (HHNS), the correct statement is to administer 6L of IV fluid over the first 24 hours (option B). The management of HHNS focuses on correcting dehydration and hyperglycemia. The initial fluid resuscitation in HHNS aims to address the profound dehydration that occurs due to osmotic diuresis from hyperglycemia. The recommended rate is to administer 1 to 1.5 L/hour of IV fluid until the patient is hemodynamically stable and urine output is adequate. Administering fluid rapidly helps to address the hypovolemia and prevent complications associated with shock. Administering fluid too slowly may delay the correction of dehydration and lead to further complications.
