Adult Health Exam 1 Chamberlain

Correct Answer: D

Rationale: In managing COPD with a metered-dose inhaler (MDI), the nurse should emphasize all of the techniques mentioned. Using a spacer can help improve drug delivery and reduce the risk of oral thrush. Synchronizing breaths with inhaler activation ensures proper medication delivery to the lungs. Regular cleaning of the inhaler prevents blockages and ensures optimal functioning. Therefore, all these techniques are important for effective COPD management, making 'All of the above' the correct answer. Choices A, B, and C are all crucial components of proper MDI technique in COPD, so they are not individually sufficient without the others.

Correct Answer: C

Rationale: The most important aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is crucial as it ensures early detection of complications such as ischemia or infection. Changing the colostomy bag only when necessary is more appropriate than doing it daily, as it prevents unnecessary changes that may irritate the skin. While eating a low-residue diet is beneficial, it is not the most crucial aspect to teach. Irrigating the colostomy should only be done if advised by a healthcare provider, as it is not a routine procedure for all clients with a colostomy.

Correct Answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

Correct Answer: D

Rationale: During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.

Correct Answer: B

Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.
