1. When administering a subcutaneous injection of insulin to a client, what angle should the nurse use for the injection?

Correct answer: C

Rationale: The correct angle for administering a subcutaneous injection, such as insulin, is 90 degrees. This angle allows for the medication to be delivered into the subcutaneous layer of tissue beneath the skin. A 45-degree angle is typically used for administering subcutaneous injections in infants or those with reduced adipose tissue, while a 60-degree angle is commonly used for intramuscular injections. A 30-degree angle is not a standard angle for subcutaneous injections.

2. When starting Alfuzosin for the treatment of Benign Prostatic Hyperplasia, a nurse is providing teaching to a client. The nurse should instruct the client that which of the following is an adverse effect of this medication?

Correct answer: C

Rationale: The correct adverse effect of Alfuzosin is hypotension. Alfuzosin relaxes muscle tone in veins, leading to decreased cardiac output and subsequent hypotension. Patients on this medication should be advised to change positions slowly to prevent a sudden drop in blood pressure. Choice A, Bradycardia, is not a common adverse effect of Alfuzosin. Choice B, Edema, is not typically associated with Alfuzosin use. Choice D, Tremor, is also not a common adverse effect of Alfuzosin.

3. What intervention is crucial during a sickle cell crisis in a child?

Correct answer: A

Rationale: Administering oxygen is crucial during a sickle cell crisis in a child as it helps to prevent further sickling of cells. Oxygen therapy can improve oxygen saturation levels, reducing the risk of tissue damage and complications. Applying cold compresses (choice B) is not recommended as it can potentially worsen vaso-occlusive crisis by causing vasoconstriction. Restricting fluids (choice C) is not appropriate as hydration is essential to prevent dehydration and maintain adequate blood flow. Encouraging bed rest (choice D) may be necessary but administering oxygen takes precedence in managing a sickle cell crisis.

4. What is typically the first sign of puberty in females?

Correct answer: A

Rationale: The correct answer is A: Breast development (thelarche) is usually the first sign of puberty in females, typically beginning between ages 8 and 13. This marks the start of puberty, followed by pubic hair growth, a growth spurt, and eventually menarche (the onset of menstruation). Pubic hair growth and axillary hair growth usually follow breast development in the sequence of pubertal changes. Therefore, the first noticeable change indicating the onset of puberty in females is the development of breast buds.

5. Which structure serves as the normal pacemaker of the heart?

Correct answer: A

Rationale: The correct answer is the SA node. The sinoatrial (SA) node is known as the natural pacemaker of the heart as it generates electrical impulses initiating each heartbeat. The SA node is located in the right atrium and sets the rhythm and rate of the heartbeat. The AV node (choice B) is responsible for delaying the electrical impulse to allow the atria to contract before the ventricles. Purkinje fibers (choice C) are specialized cardiac fibers responsible for the rapid conduction of impulses to the myocardial cells, and the atria (choice D) are the upper chambers of the heart involved in receiving blood from the veins.
