Correct Answer: D

Rationale: When assessing for costovertebral angle tenderness, sharp pain on percussion of the area indicates inflammation of the kidney or paranephric area. The correct technique involves placing one hand over the 12th rib, at the costovertebral angle, and thumping that hand with the ulnar edge of the other fist. The client normally feels a thud and should not experience pain. Ovarian infection, liver enlargement, or spleen enlargement are not associated with the costovertebral angle tenderness. Therefore, the correct answer is kidney inflammation.

Correct Answer: A

Rationale: When working in a community pediatric health clinic, applying the principles of initiative is crucial when caring for preschool children. According to Erik Erikson's psychosocial theory, the developmental task for preschool children is initiative. Preschool children are in the stage where they are eager to initiate activities and carry out tasks. This stage is characterized by a balance between initiative and guilt. By encouraging children to explore and take the initiative in a supportive environment, healthcare providers can foster their sense of independence and creativity. The other choices are incorrect because: - Sensorimotor thought is a term associated with Jean Piaget's cognitive development theory, not Erikson's psychosocial theory. - Intimacy is a developmental task associated with young adults, not adolescents, in Erikson's theory. - Concrete operations is a term linked to Piaget's theory of cognitive development and is not a developmental task according to Erikson's psychosocial theory.

Correct Answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.

Correct Answer: C

Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

Correct Answer: C

Rationale: The correct answer is 'certain diet and foods.' Risk factors that increase the chances of getting skin cancer include having a light or fair complexion, a history of bad sunburns, personal or family history of skin cancer, outdoor activities with sun exposure, exposure to X-rays or radiation, exposure to certain chemicals, repeated trauma or injury resulting in scars, age over 50, male gender, and living in specific geographic locations. These factors can contribute to the development of skin cancer. Avoiding exposure to the sun, using protective clothing and sunscreen, and regular skin inspections are key preventive measures. Choice C, 'certain diet and foods,' is incorrect as diet is not a primary risk factor for skin cancer. Options A, B, and D are all valid risk factors associated with an increased risk of developing skin cancer.
