Correct Answer: C

Rationale: The correct answer is C. Limiting intake of beef to 4 ounces per week is an effective dietary modification to manage high cholesterol. Choice A is incorrect because the frequency and duration of exercise alone may not be sufficient to lower cholesterol significantly. Choice B is incorrect as proteins, including lean sources like poultry and fish, can be a part of a healthy diet. Choice D is incorrect as low-density lipoproteins, known as bad cholesterol, should be decreased, not increased, for heart health.

Correct Answer: D

Rationale: The client in this scenario is in the illness stage of infection. During this stage, the individual exhibits specific symptoms such as a severe sore throat, pain when swallowing, and swollen lymph nodes. The prodromal stage precedes the appearance of specific symptoms and is characterized by nonspecific signs. The incubation period occurs between exposure to the pathogen and the onset of symptoms. Convalescence is the recovery period following the resolution of the infection. Therefore, the correct answer is 'D: Illness' as it aligns with the symptoms presented by the client.

Correct Answer: D

Rationale: When assessing the way a patient walks, the healthcare provider is evaluating the gait, which refers to a particular manner or style of walking. Body alignment pertains to the positioning of body parts in relation to one another, range of motion refers to the extent of movement of a joint, and activity tolerance relates to the ability to endure physical activities. In this scenario, observing the patient's walking pattern specifically focuses on gait assessment.

Correct Answer: D

Rationale: The correct answer is D. When a client has vision loss, using a clock pattern to describe food placement on the plate can facilitate independent eating. This method enables the client to locate different food items based on their positions, enhancing self-feeding abilities. Instructing the client on the sequence of foods to eat first (Choice A) may not address the visual impairment directly. Providing small-handle utensils (Choice B) can be helpful for clients with limited dexterity but may not specifically assist a client with vision loss. Thickening liquids (Choice C) is more relevant for clients with dysphagia, not vision loss.

Correct Answer: B

Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
