Which contraction generates the least force?

Correct Answer: D

Rationale: The correct answer is D: Fast concentric. Fast concentric contractions generate the least force because the muscle shortens quickly, leading to lower tension production compared to slow concentric contractions. In fast eccentric contractions (choice B), the muscle lengthens quickly, which can produce more force as it resists against gravity or an external load. Slow eccentric contractions (choice A) involve controlled lengthening of the muscle, resulting in higher force production compared to fast concentric contractions. Slow concentric contractions (choice C) involve controlled shortening of the muscle, leading to higher force production than fast concentric contractions.

Correct Answer: A

Rationale: The correct answer is A: Hepatitis A. Jaundice without risk factors for other types of hepatitis indicates an acute infection, which is most commonly caused by Hepatitis A virus. This virus is usually transmitted through contaminated food or water, making it more likely for a daycare worker to contract due to close contact with children. Hepatitis B is typically transmitted through blood or sexual contact, which the worker denies. Hepatitis C is also transmitted through blood, which is not reported. Hepatitis D requires Hepatitis B infection for replication, and since Hepatitis B is not indicated in this case, Hepatitis D is unlikely.

Correct Answer: C

Rationale: The correct answer is C: Checked for patency of the ulnar artery. The Allen test is used to assess the collateral circulation of the hand before arterial blood sampling from the radial artery. This involves occluding both the ulnar and radial arteries and then releasing pressure on the ulnar artery while observing the return of color to the hand. If the ulnar artery is patent, the hand should regain color within 5-10 seconds, indicating adequate collateral circulation. This is important to prevent ischemic complications. Choice A (Checked for patency of the radial artery) is incorrect because the Allen test specifically evaluates the ulnar artery's patency, not the radial artery. Choice B (Checked for patency of the brachial artery) is incorrect because the Allen test focuses on the collateral circulation in the hand, not the brachial artery. Choice D (Checked for patency of the femoral artery) is incorrect because the Allen test is not used to assess the femoral artery

Correct Answer: D

Rationale: The correct answer is D. Calling the physician immediately is crucial because a severe headache in a client with a cerebral aneurysm may indicate a rupture, a life-threatening emergency. The physician needs to be notified promptly for urgent intervention. Reassessing the client in 15 minutes (Choice A) may delay necessary action. Administering an analgesic (Choice B) without knowing the underlying cause of the headache could mask symptoms and delay appropriate treatment. Informing the nurse manager (Choice C) is not the priority; direct communication with the physician for immediate medical intervention is essential in this situation.

Correct Answer: B

Rationale: The correct answer is B: Using a cuff that covers two-thirds of the patient's upper arm. This is essential for obtaining an accurate blood pressure reading because using a cuff that is too small can result in falsely elevated readings, while using a cuff that is too large can result in falsely low readings. By covering two-thirds of the upper arm, the cuff ensures proper compression of the brachial artery, allowing for an accurate measurement. A: Positioning the patient's arm above the level of the heart is not essential for obtaining an accurate reading and can lead to inaccurate results. C: Deflating the cuff at a rate of 5-10 mm Hg per second is important but not as crucial as using the correct cuff size. D: Having the patient stand during the measurement is not recommended as blood pressure should be measured with the patient in a seated or lying position for accuracy.
