Which is characteristic of newborns whose mothers smoked during pregnancy?
- A. Large for gestational age
- B. Preterm, but size appropriate for gestational age
- C. Growth retardation in weight only
- D. Growth retardation in weight, length, and head circumference
Correct Answer: D
Rationale: Newborns whose mothers smoked during pregnancy often display growth retardation in weight, length, and head circumference. Maternal smoking is associated with intrauterine growth restriction, leading to reduced size parameters at birth. This can result in newborns being smaller in weight, length, and head circumference compared to newborns of mothers who did not smoke during pregnancy. Smoking during pregnancy can have negative effects on the developing fetus, contributing to various health risks and growth abnormalities in newborns.

is softening of the bones as result of nutritional deficiencies or limited exposure to sunlight :
- A. COXA
- B. scoliosis
- C. Rickets
- D. Talipes
Correct Answer: C
Rationale: Rickets is a condition that involves softening and weakening of the bones in children, usually due to a vitamin D deficiency, inadequate calcium intake, or lack of exposure to sunlight. Vitamin D is essential for the absorption of calcium and phosphorus in the body, which are important for bone health. Without sufficient vitamin D, the body is unable to properly mineralize the bones, leading to softening and deformities. Common symptoms of rickets include bowed legs, delayed growth, and muscle weakness. Treatment typically involves vitamin D supplementation, dietary changes, and adequate exposure to sunlight.
An adolescent asks the nurse what causes primary dysmenorrhea. The nurse's response should be based on which statement?
- A. It is an inherited problem.
- B. Excessive estrogen production causes uterine pain.
- C. There is no physiologic cause; it is a psychological reaction.
- D. There is a relation between prostaglandins and uterine contractility.
Correct Answer: D
Rationale: Primary dysmenorrhea is painful menstruation that occurs without any underlying gynecological conditions, such as endometriosis. The cause of primary dysmenorrhea is related to the release of prostaglandins during menstruation. Prostaglandins are lipid compounds that act as chemical messengers in the body, causing the uterus to contract and shed its lining during menstruation. High levels of prostaglandins can lead to increased uterine muscle contractions, resulting in pain. Therefore, the nurse should explain to the adolescent that there is a relation between prostaglandins and uterine contractility as the cause of primary dysmenorrhea.
Parents report that they have been giving a multivitamin to their 1-year-old infant. The nurse counsels the parents that which vitamin can cause a toxic reaction at a low dose?
- A. Niacin
- B. B
- C. D
- D. C
Correct Answer: C
Rationale: Vitamin D is a fat-soluble vitamin that can be toxic in high doses, leading to hypercalcemia. Infants are particularly vulnerable to vitamin D toxicity because they have a lower ability to excrete excess vitamin D. Symptoms of vitamin D toxicity include nausea, vomiting, weakness, and kidney problems. Therefore, it is important for parents to avoid giving high doses of vitamin D to infants and always follow healthcare provider recommendations for supplementation.
ahmed 2 months old come to emergency department with epistaxis and prolong PTT, clotting and bleeding time , what you suspect ahmed have :
- A. thalassemia
- B. hemophilia
- C. leukemia
- D. sickle anemia
Correct Answer: B
Rationale: Ahmed is presenting with epistaxis (nosebleed) and prolonged PTT (partial thromboplastin time), clotting time, and bleeding time, which are indicative of a bleeding disorder. Given the symptoms and lab findings, hemophilia is the most likely cause. Hemophilia is an inherited bleeding disorder characterized by deficiency or dysfunction of clotting factors, particularly Factor VIII (hemophilia A) or Factor IX (hemophilia B). Patients with hemophilia often present with spontaneous bleeding episodes, such as nosebleeds, bruising, and prolonged bleeding after injury or surgery. Thalassemia, leukemia, and sickle cell anemia are not associated with prolonged clotting times and bleeding presentations, making hemophilia the most appropriate choice in this scenario.
When administering spironolactone (Aldactone) to a client who has had a unilateral adrenalectomy, the nurse should instruct the client about which of the following possible adverse effects of the drug?
- A. Breast tenderness
- B. Increased facial hair
- C. Menstrual irregularities
- D. Hair loss
Correct Answer: C
Rationale: Spironolactone (Aldactone) is a potassium-sparing diuretic and aldosterone antagonist that is commonly used to treat conditions such as hypertension, heart failure, and edema. One of its common side effects is hormonal effects due to its antiandrogenic properties. In women, spironolactone can lead to menstrual irregularities, including amenorrhea (absence of menstrual periods) or breakthrough bleeding. Therefore, in a client who has had a unilateral adrenalectomy (removal of one adrenal gland), which can already disrupt hormonal balance, the nurse should educate the client about the potential for menstrual irregularities when taking spironolactone.
