A nurse is teaching a client who has glaucoma and a new prescription for timolol eyedrops. Which of the following statements by the client indicates an understanding of the teaching?
"I should expect my tears to turn a red color after using the eye drops."
"I will put pressure on the corner of my eye after using the eye drops."
"The drops should be placed in the center of my eye."
"These drops will improve my cloudy vision."
The Correct Answer is B
A. "I should expect my tears to turn a red color after using the eye drops.": Timolol does not cause red discoloration of tears. Redness of the eye may indicate irritation, allergy, or another adverse effect, so the client should report persistent redness rather than expect it as normal.
B. "I will put pressure on the corner of my eye after using the eye drops.": Applying gentle pressure to the nasolacrimal duct (inner corner of the eye) after instilling timolol reduces systemic absorption and potential systemic side effects, such as bradycardia or hypotension. This technique demonstrates proper administration and understanding of safety precautions.
C. "The drops should be placed in the center of my eye.": Eye drops should be instilled into the lower conjunctival sac, not directly onto the center of the cornea, to reduce irritation and maximize absorption. Placing drops on the cornea can cause discomfort and reduce effectiveness.
D. "These drops will improve my cloudy vision.": Timolol lowers intraocular pressure but does not restore vision or improve cloudiness caused by glaucoma. The goal of therapy is to prevent progression of vision loss, not to reverse existing damage.

Correct Answer is D
Explanation
A. "Hair growth in the pubic area begins before breast development.": In females, breast development (thelarche) typically precedes pubic hair growth (pubarche). This statement is inaccurate and does not reflect the normal sequence of pubertal changes.
B. "Puberty begins with a female's first menstrual cycle.": Menarche occurs later in puberty, usually around Tanner stage 3–4, and is not the initial sign of pubertal development. Puberty begins with the onset of breast development and other secondary sexual characteristics.
C. "Females will stop growing by the age of 14.": Growth in females continues for several years after the onset of puberty, often until 16–18 years of age, depending on the timing of menarche and individual growth patterns. Stating age 14 is inaccurate.
D. "Females begin puberty about 2 years earlier than males.": This statement is accurate. On average, females begin puberty between ages 8–13, while males typically start between ages 10–15, reflecting the earlier onset of secondary sexual characteristics in females.
Correct Answer is D
Explanation
A. Potassium level: Potassium measurement is used to assess electrolyte balance and kidney function, but it does not provide information about platelet function or clotting ability. It is not relevant for evaluating petechiae or ecchymoses.
B. Prealbumin: Prealbumin is a marker of nutritional status and protein intake. While important for overall health, it does not help identify the cause of bleeding disorders or thrombocytopenia.
C. Creatinine clearance: Creatinine clearance assesses renal function and is unrelated to platelet levels or coagulation abnormalities. It would not provide diagnostic information for clients presenting with bleeding manifestations.
D. Platelet count: A platelet count is essential for evaluating clients with generalized petechiae and ecchymoses because these signs suggest thrombocytopenia or platelet dysfunction. Measuring platelet levels helps determine the severity of the disorder and guides further diagnostic and therapeutic interventions.
