The physician has prescribed Cognex (tacrine) for a client with dementia. The nurse should monitor the client for adverse reactions, which include:

Correct Answer: B

Rationale: Elevated liver enzymes are a key adverse reaction to Cognex, requiring monitoring in dementia appetite, BP, and memory aren't primary concerns. Nurses check LFTs, ensuring safety, critical for managing Alzheimer's medication risks.

Correct Answer: B

Rationale: Fresh fruit is naturally low in sodium and is a suitable choice for a low-sodium diet. It provides essential nutrients without adding significant amounts of sodium, making it a healthy option for individuals following a low-sodium diet. Canned soup, pickles, and soy sauce are high in sodium content and should be avoided by individuals on a low-sodium diet. Canned soups are often loaded with added salt, pickles are preserved in brine containing high sodium levels, and soy sauce is a condiment with a high sodium content.

Correct Answer: B

Rationale: When a client is on a soft diet, it is important to offer foods that are easy to chew and swallow. Mashed potatoes are a suitable choice for a soft diet as they are soft in texture and easy to digest. Fresh apples, raw carrots, and nuts are harder and may not be appropriate for a soft diet. Fresh apples and raw carrots require more chewing, and nuts are hard and crunchy, which can be difficult for someone on a soft diet to consume. Therefore, mashed potatoes are the correct option for a client on a soft diet.

Correct Answer: B

Rationale: When administering a subcutaneous injection, inserting the needle at a 90-degree angle is appropriate. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Using a 1-inch needle is common for subcutaneous injections to reach the subcutaneous fat layer adequately. Tuberculin syringes are typically used for intradermal injections, not subcutaneous injections. Aspirating before injecting is not necessary for subcutaneous injections as it is primarily used for intramuscular injections to ensure the needle is not in a blood vessel.

Correct Answer: C

Rationale: When following a low-fat diet, it is essential to choose foods that are low in fat. Chicken breast is a lean protein source that is low in fat, making it a suitable option for a low-fat diet. Bacon, whole milk, and cheese are higher in fat content and should be avoided or limited in a low-fat diet. Bacon is high in saturated fat, whole milk contains significant amounts of fat, including saturated fat, and cheese is also high in fat. Therefore, these options are not ideal for a low-fat diet.
