Correct Answer: B

Rationale: The correct answer is to ask the client to perform a calculation that involves working memory and processing skills. This question not only assesses the recent memory but also evaluates attention and executive functioning. The choice 'I am going to say the names of three things, and I want you to repeat them after me: blue, ball, pen' assesses immediate recall rather than recent memory. Asking about the current year or season tests orientation rather than recent memory. Inquiring about the watch and its purpose assesses comprehension and judgment rather than recent memory.

Correct Answer: C

Rationale: Osteomyelitis is an infection in the bone that can be caused by bacteria reaching the bone either from outside the body (such as through an open fracture) or inside the body (such as through the bloodstream). This response provides a concise and accurate explanation of osteomyelitis, making it the best choice. Choices A and B provide inaccurate information about the condition, attributing it to age-related bone breakdown and Vitamin D deficiency, which are not correct causes of osteomyelitis. Choice D deflects the question instead of providing the patient with a clear explanation, making it an inappropriate response.

Correct Answer: B

Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.

Correct Answer: C

Rationale: A client with a severe vitamin C deficiency has a condition called scurvy. Scurvy is characterized by symptoms such as bleeding gums, loose teeth, poor wound healing, and easy bruising. The correct answer is 'Bleeding gums and loose teeth' because these are classic signs of scurvy due to vitamin C deficiency. Choice A ('Cracks at the corners of the mouth') is more indicative of a deficiency in B vitamins, specifically riboflavin. Choice B ('Altered mental status') is not typically associated with vitamin C deficiency but can occur with other conditions like vitamin B12 deficiency. Choice D ('Anorexia and diarrhea') are not common symptoms of vitamin C deficiency, as they are more commonly associated with other gastrointestinal issues or deficiencies in different nutrients.

Correct Answer: C

Rationale: A hydrocele is a collection of fluid in the scrotum that results from a patent tunica vaginalis. Illumination of the scrotum with a pocket light demonstrates the clear fluid. In most cases, the fluid reabsorbs within the first few months of life and no treatment is necessary. Massaging the groin area (Choice A) is not recommended as it will not help in the resolution of the hydrocele. Referral to a surgeon (Choice B) is not necessary at this stage since hydroceles often resolve on their own in infants. Keeping the infant in a flat, supine position (Choice D) does not aid in the reabsorption of fluid and is not a recommended intervention for hydrocele management.
