During an assessment, the nurse notices clouding of the lens of the left eye, and the client reports blurred and hazy vision in the eye. These findings suggest which of the following?
Otosclerosis
Cataracts
Presbycusis
Glaucoma
The Correct Answer is B
A. Otosclerosis: Otosclerosis refers to abnormal bone growth in the middle ear, leading to hearing loss, not vision problems. It affects hearing, not the eyes, and does not cause blurred or hazy vision.
B. Cataracts: Cataracts occur when the lens of the eye becomes clouded, leading to blurred or hazy vision, which is exactly what the client is describing. The clouding of the lens is a hallmark sign of cataracts, which typically cause gradual vision loss over time.
C. Presbycusis: Presbycusis is age-related hearing loss, not a visual issue. It typically manifests as difficulty hearing high-frequency sounds and is not associated with blurred vision or clouding of the lens.
D. Glaucoma: Glaucoma is characterized by increased intraocular pressure, which can lead to vision loss, but it typically causes peripheral vision loss, not blurred or hazy vision. The clouding of the lens described here is more indicative of cataracts than glaucoma.

Correct Answer is C
Explanation
A. Increased balance: Aging typically results in decreased balance due to changes in the musculoskeletal and nervous systems. Older adults often experience a decline in coordination and proprioception, which can increase the risk of falls.
B. Increased muscle mass: Muscle mass generally decreases with age, a condition known as sarcopenia. This loss contributes to reduced strength and endurance, making physical activity and mobility more difficult for older adults.
C. Increased joint stiffness: Joint stiffness is a common age-related change caused by decreased synovial fluid, cartilage wear, and reduced flexibility. This can limit mobility and make daily activities more challenging for elderly clients.
D. Increased calcification of bones: With aging, bones tend to lose density and become more porous, leading to conditions like osteoporosis. Calcification may occur in soft tissues, but bone itself typically becomes weaker, not more calcified.
Correct Answer is ["0.57"]
Explanation
Identify the desired dose: 200 mg
Identify the available concentration for IM administration: The package insert information states that "Each 1 mL of solution contains approximately 350 mg equivalent of ceftriaxone." So, the available concentration is 350 mg/mL.
Calculate the volume to administer (mL):
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 200 mg / 350 mg/mL
= 0.5714... mL
Round the answer to the nearest hundredth:
= 0.57 mL
