A nurse assesses an 83-year-old female's venous ulcer for the second time that is located near the right medial malleolus. The wound is exhibiting purulent drainage, and the patient has limited mobility in her home. Which of the following is the best course of action?

Correct Answer: A

Rationale: The correct course of action is to encourage warm water soaks to the right foot. This can help promote wound healing and alleviate discomfort. Before recommending increased activity or notifying additional team members, it is crucial to assess arterial blood flow by determining the patient's pulse in the right ankle. Poor arterial blood flow could worsen the condition, making increased activity inappropriate. While notifying the case manager of purulent drainage is important, addressing the wound care directly should be the primary focus at this stage.

Correct Answer: C

Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding compared to the other conditions listed. Pernicious anemia is a condition resulting from vitamin B12 deficiency due to the absence of intrinsic factor, necessary for B12 absorption. While pernicious anemia can lead to neurological issues, it is not directly linked to an increased risk of bleeding. Metastatic liver cancer can cause liver dysfunction leading to coagulopathy, gram-negative septicemia can result in disseminated intravascular coagulation (DIC), and iron-deficiency anemia can lead to microcytic hypochromic red blood cells, increasing the risk of bleeding. Therefore, pernicious anemia is the least likely to be associated with an increased potential for bleeding out of the options provided.

Correct Answer: C

Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer. Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects. Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia. Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.

Correct Answer: D

Rationale: The patient's presentation of a warm, red, swollen extremity with a low fever is indicative of cellulitis, which is inflammation of cellular tissue. Cellulitis is commonly associated with these symptoms due to a bacterial infection in the skin and underlying tissues. Herpes (Choice A) is a viral infection that typically presents with grouped vesicles, not the warm, red, swollen presentation seen in cellulitis. Scleroderma (Choice B) is a chronic autoimmune condition affecting the skin and connective tissue, presenting differently from the acute symptoms of cellulitis. Dermatitis (Choice C) refers to skin inflammation, which does not typically present with the described symptoms of warmth, redness, swelling, and low fever observed in cellulitis.

Correct Answer: A

Rationale: The correct answer is 'A 12-month-old that does not 'cruise''. At 12 months, a child should at least be 'cruising' (holding on to objects to walk), which is considered pre-walking. The other choices describe age-appropriate developmental milestones: sitting upright unsupported by 8 months, rolling prone to supine by 6 months, and rolling supine to prone by 3 months. Not 'cruising' at 12 months may indicate a delay in motor skills development.

Correct Answer: D

Rationale: Clients with renal disease are prone to hyperkalemia due to impaired kidney function, making it crucial for them to avoid foods high in potassium to prevent further complications. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk of hypokalemia. These individuals should actually consume foods high in potassium to replenish the electrolyte lost through diuresis, ileostomy output, or metabolic alkalosis.

Correct Answer: D

Rationale: Signs of impaired breathing in infants and children typically include nasal flaring, grunting, and seesaw breathing. Nasal flaring is the widening of the nostrils during breathing to help with air intake, grunting is a sound made during expiration to keep the airway open, and seesaw breathing is an abnormal pattern where the chest moves in while the abdomen moves out. Quivering lips are not a typical sign of impaired breathing in infants and children, making it the correct answer. Nasal flaring, grunting, and seesaw breathing are all signs indicating the need for immediate medical attention due to potential respiratory distress.

Correct Answer: A

Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.

Correct Answer: C

Rationale: The correct statement is that Guillain-Barre Syndrome causes muscle weakness in the legs. This muscle weakness typically starts in the legs and can progress to the upper body. Choice A is incorrect as while most cases do improve, the recovery time can vary. Choice B is incorrect as Guillain-Barre Syndrome primarily affects muscle weakness rather than sensation. Choice D is incorrect as severe cases of Guillain-Barre Syndrome can lead to respiratory muscle weakness, impacting breathing.
