The nurse is reinforcing teaching of proper foot care to a client with diabetes mellitus. Which statement by the client indicates the need for further teaching?
- A. I will apply lanolin to my feet to prevent dry skin
- B. I will avoid applying a heating pad directly to my feet
- C. I will test the water with a thermometer before bathing
- D. I will wear sandals instead of sneakers to prevent moisture.
Correct Answer: D
Rationale: Sandals (D) expose feet to injury, increasing infection risk in diabetes. Lanolin (A), avoiding heating pads (B), and testing water (C) are correct to prevent skin breakdown and burns.

The nurse is caring for a client who has a single-chamber atrial pacemaker. Which of the following findings would the nurse expect to observe on the client’s electrocardiogram strip?
- A. Pacemaker spike on the T wave
- B. Pacemaker spike before the P wave
- C. Occasional wide and distorted QRS complex
- D. Prolonged PR interval with normal QRS complex
Correct Answer: B
Rationale: A single-chamber atrial pacemaker paces the atrium, producing a spike before the P wave (B), followed by normal conduction. Spikes on T waves (A) are abnormal, wide QRS (C) suggests ventricular issues, and prolonged PR (D) is unrelated to pacing.
After a recent outbreak of varicella in an elementary school, the practical nurse is assisting with the development of an informative letter to parents. Which of the following instructions are appropriate to include? Select all that apply.
- A. Apply calamine lotion to soothe lesions
- B. Clip your child’s fingernails short
- C. Ensure that your child’s vaccinations are up to date
- D. Keep your child home until lesions have crusted
- E. Place mittens on your child’s hands when sleeping
Correct Answer: A,B,C,D,E
Rationale: Calamine lotion (A) relieves itching, short nails (B) and mittens (E) prevent scratching, vaccinations (C) protect against future infection, and isolation until crusted (D) prevents transmission. All are appropriate.
All nursing staff on the medical unit are responsible for implementing a new interdisciplinary fall prevention protocol. Which duties are appropriate for the licensed practical nurse to delegate to unlicensed assistive personnel to promote client safety? Select all that apply.
- A. Educate newly admitted client on the importance of using the call light for assistance
- B. Place the bedside commode as close to the bed as possible
- C. Remind client to change position slowly
- D. Report observations of changes in client’s condition immediately
- E. Report whether client is using correct gait and balance while ambulating with walker
Correct Answer: B,C,D
Rationale: UAP can place commodes (B), remind about slow position changes (C), report condition changes (D), and observe gait (E). Education (A) requires nursing judgment, unsuitable for delegation.
Prior to discharge of a child with a ventriculoperitoneal (VP) shunt, the nurse reinforces teaching to the caregiver about when to contact the health care provider. The caregiver shows understanding of the instructions by contacting the health care provider about which symptom?
- A. A temperature of 98.6°F (37.2°C) that occurs during the evening
- B. The child cannot recall items eaten for lunch the previous day
- C. The child vomits after awakening from a nap and again 1 hour later
- D. The VP shunt is palpable along the posterolateral portion of the skull
Correct Answer: C
Rationale: Persistent vomiting (C) suggests shunt malfunction or increased intracranial pressure, requiring immediate reporting. Normal temperature (A), memory lapses (B), and palpable shunt (D) are not concerning.

The nurse is reinforcing teaching for a client who is prescribed acyclovir for genital herpes. Which statement should be included by the nurse?
- A. Activated PTT(62%)
- B. Hemotocrit(5%)
- C. Platelets(23%)
- D. PT(8%)
Correct Answer: A
Rationale: Heparin is an anticoagulant that helps prevent further clot formation. It is titrated based on activated partial
thromboplastin time (aPTT). The therapeutic aPTT target is 1.5-2.0 times the normal reference range of 30-40
seconds. A aPTT value >100 seconds would be considered critical and could result in life-threatening side
effects. Common sentinel events that result from heparin drips include epistaxis, hematuria, and gastrointestina
bleeds (Option 1).
(Option 2) A normal hematocrit for a female is 37%-47% (0.37-0.47). In a client with a history of chronic
anemia, a hematocrit of 30% (0.30) may be an expected finding.
(Option 3) A normal platelet count is 150,000-400,000/mm* (150-400 x 10%L). In a client with a history of liver
cirrhosis, a platelet count of 80,000/mmª (80 x 10%/L) would be anticipated. An episode of bleeding rarely occurs
with a platelet count >50,000 mm* (50 x 10%/L).
(Option 4) A normal prothrombin time is 11-12.5 seconds, and so a level of 11 seconds would not be
concerning.
