Nursing Elites

1. In a 68-year-old man, a gradual loss of hearing is known as _____________.

• A. presbycusis
• B. xerostomia
• C. myopia
• D. presbyopia

Correct answer: A

Rationale: The correct answer is 'presbycusis.' Presbycusis is the age-related gradual loss of hearing ability, commonly seen in the elderly population. Xerostomia refers to dry mouth, myopia is nearsightedness, and presbyopia is the age-related loss of the eye's ability to focus on close objects. Given Mr. Roberts' age and symptom of gradual hearing loss, presbycusis is the most likely diagnosis. Xerostomia, myopia, and presbyopia do not match the sensory change described in the question, making them incorrect choices.

2. Each small square on the EKG paper is:

• A. 0.04 seconds long and 5mm tall
• B. 0.2 seconds long and 5mm tall
• C. 0.04 seconds long and 20mm tall
• D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

3. In a patient with acromegaly, which assessment finding will the nurse expect to find?

• A. Sternal deformity and hyperextensible joints
• B. Growth retardation and a delayed onset of puberty
• C. Overgrowth of bone in the face, head, hands, and feet
• D. Increased height and weight and delayed sexual development

Correct answer: C

Rationale: Acromegaly is a condition characterized by excessive secretion of growth hormone in adulthood after normal body growth completion. This hormonal excess leads to overgrowth of bones in the face, head, hands, and feet; however, there is no significant change in height. Stating sternal deformity and hyperextensible joints is incorrect as they are characteristic findings of Marfan syndrome. Growth retardation and delayed onset of puberty are not typical of acromegaly but are seen in hypopituitary dwarfism. Increased height, weight, and delayed sexual development are features of gigantism, not acromegaly. Therefore, the correct assessment finding in a patient with acromegaly would be overgrowth of bone in the face, head, hands, and feet.

4. Where is the Loop of Henle located in the body?

• A. Liver
• B. Kidney
• C. Heart
• D. Ear

Correct answer: B

Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.

5. Why should direct care providers avoid glued-on artificial nails?

• A. Interfere with dexterity of the fingers.
• B. Could fall off in a patient's bed.
• C. Harbor microorganisms.
• D. Can scratch a patient.

Correct answer: C

Rationale: Direct care providers, including nurses, should avoid glued-on artificial nails because studies have shown that artificial nails, especially when cracked, broken, or split, create crevices where microorganisms can thrive and multiply. This can lead to an increased risk of transmitting infections to patients. Therefore, the primary reason for avoiding glued-on artificial nails is their potential to harbor harmful microorganisms, making option C the correct choice. Options A, B, and D are incorrect because while they may present some issues, the primary concern is the risk of microbial contamination associated with artificial nails.
