Nokea
Bones that form the roof and the upper part of the sides of the cranium
- A. Frontal bone
- B. Temporal bone
- C. Parietal bone
- D. Occipital bone
Correct Answer: C
Rationale: The correct answer is C: Parietal bone. The parietal bone forms the roof and upper part of the sides of the cranium. It articulates with other bones, such as the frontal, temporal, and occipital bones, to create the structure of the skull. The frontal bone (A) forms the forehead, the temporal bone (B) is located on the sides of the skull, and the occipital bone (D) forms the back and base of the skull. Therefore, the parietal bone is the only bone among the choices that specifically fits the description of forming the roof and upper part of the sides of the cranium.

The accessory glands of the male reproductive system are:
- A. corpus spongiosum;
- B. corpus cavernosum;
- C. penis;
- D. seminal vesicles;
Correct Answer: D
Rationale: The correct answer is D: seminal vesicles. Seminal vesicles are accessory glands that produce a significant portion of the fluid that makes up semen. They contribute nutrients and substances that support sperm viability and motility. Choices A, B, and C are incorrect as they are structures of the penis involved in erection and urination, not accessory glands of the male reproductive system.
Three days after having a pelvic exenteration procedure, a client suddenly complains of a 'giving' sensation along her abdominal incision. You check under the dressing and find that the wound edges are open and loops of intestine are protruding. Which action should you take first?
- A. Call the client's surgeon and report that wound evisceration has occurred.
- B. Cover the wound with saline-soaked dressings.
- C. Don sterile gloves and gently replace the intestine back in the wound.
- D. Check the client's blood pressure and heart rate.
Correct Answer: B
Rationale: Covering the exposed tissue with saline-soaked dressings prevents drying and reduces risk of further complications.
You have obtained these data about a 68-year-old client who is ready for discharge from the ED and has a new prescription for nitroglycerin (Nitro-Stat) 0.4 mg sublingual. Which information about the client has the most immediate implications for client teaching?

- B. The client's father and two brothers all have had myocardial infarctions.
- C. The client uses sildenafil (Viagra) several times weekly for erectile dysfunction.
- D. The client is unable to remember when he first experienced chest pain.
Correct Answer: C
Rationale: Sildenafil and nitroglycerin together can cause severe hypotension; this interaction must be addressed immediately.
The transmission of sound vibrations through the inner ear occurs chiefly through:
- A. Bone
- B. Nerve fibers
- C. Air
- D. Liquid
Correct Answer: D
Rationale: The correct answer is D: Liquid. Sound vibrations travel through the inner ear mainly through the liquid-filled cochlea. When sound waves reach the ear, they cause the fluid inside the cochlea to move, stimulating hair cells that convert the vibrations into electrical signals sent to the brain. Choice A (Bone) is incorrect as bone conduction bypasses the middle ear, while sound must pass through it to reach the cochlea. Choice B (Nerve fibers) is incorrect because nerves transmit the electrical signals generated by the hair cells, not sound vibrations themselves. Choice C (Air) is incorrect as the inner ear is filled with liquid, not air, and sound waves need a medium like air to travel through the ear canal but not inside the inner ear.
A chancre usually appears on the external genitalia in which of the following condition:
- A. Syphilis
- B. Gonorrhea
- C. Trichomoniasis
- D. Herpes genitalis
Correct Answer: A
Rationale: Rationale: A chancre is a painless ulcer that is characteristic of primary syphilis infection. It usually appears on the external genitalia as a result of Treponema pallidum infection. This is distinct from the other conditions listed: Gonorrhea presents with urethritis and discharge, Trichomoniasis with vaginal discharge and irritation, and Herpes genitalis with painful vesicles or ulcers. Syphilis is the only condition among the choices that typically presents with a chancre on the external genitalia.
